SUMMARY:Math Science Lectures in Honor of Raoul Bott | Daniel Litt\, U Toronto
DESCRIPTION:Dates: October 19 & 21\, 2026 \nTime: 4:00–5:00 pm ET \nLocation: Science Center – Zimmer Hall Lecture Hall D\, 1 Oxford Street\, Cambridge MA & via Zoom Webinar \n  \nSpeaker: Daniel Litt\, University of Toronto & Benedict H. Gross Distinguished Visitor\, Harvard Mathematics Department \nMonday\, October 19\, 2026 \nLecture 1: The arithmetic of differential equations \nAbstract: When does an algebraic differential equation have solutions which are themselves algebraic functions? This question goes back at least to Fuchs\, in 1875. Its conjectural answer\, due to Grothendieck and Katz in the linear case and Ekedahl-Shepherd-Barron-Taylor and Bost in general\, situates it as one of number theory.

Taking this analogy seriously\, we should expect *every* structure on cohomology to have an analogue in this “non-abelian” setting.

SUMMARY:CMSA/Tsinghua Math-Science Literature Lecture: Robert Gompf: On classifying smoothings of R^4–from the beginning to the present
DESCRIPTION:CMSA/Tsinghua Math-Science Literature Lecture \nDate: September 16\, 2026 \nTime: 9:00 – 10:30 am ET \nLocation: CMSA G10\, 20 Garden Street & via Zoom Webinar \n  \n \nSpeaker: Robert E. Gompf\, University of Texas\, Austin \nTitle: On classifying smoothings of R^4–from the beginning to the present \nAbstract: The field of 4-manifold topology was born around 1981 with two independent revolutionary breakthroughs\, by Fields medalists Michael Freedman and Simon Donaldson. Freedman showed that topological 4-manifolds obeyed the well-developed theory of higher-dimensional manifolds\, while Donaldson used nonlinear analysis (gauge theory) to show that smooth 4-manifolds are quite different from their high-dimensional counterparts. The clash between the two theories makes 4-manifold topology uniquely intricate within manifold theory. One of the most startling consequences is that unlike in other dimensions\, Euclidean 4-space R^4 admits exotic smoothings. Equivalently\, there are smooth 4-manifolds that are homeomorphic\, but not diffeomorphic\, to R^4. We will trace the classification theory of these manifolds from their discovery to the most recent development (joint with Aristotelis Panagiotopoulos) that they cannot be classified by any countable family of numerical invariants. \n  \n\nBeginning in Spring 2020\, the CMSA began hosting a lecture series on literature in the mathematical sciences\, with a focus on significant developments in mathematics that have influenced the discipline\, and the lifetime accomplishments of significant scholars. \n  \n

SUMMARY:Ahlfors Lectures: Mohammed Abouzaid
DESCRIPTION:Ahlfors Lectures  \nDates: September 16 & 17\, 2026 \nTime: 4:00–5:00 pm \nLocation: Science Center Hall A \nSpeaker: Mohammed Abouzaid (Stanford) \nRegister to attend in person or online at: https://www.math.harvard.edu/event/ahlfors-lecture-series-mohammed-abouzaid/ \n  \n \n  \nSeptember 16\, 2026 \nTitle: Framed bordism and nearby Lagrangians \nAbstract: The problem of understanding Lagrangian embeddings in symplectic manifolds remains a mystery. The simplest class of symplectic manifolds are the cotangent bundles of smooth manifolds\, which is the setting for the most prominent open problem in the subject: Arnold’s nearby Lagrangian conjecture which asserts the connectedness of the space of Lagrangians for which the relative class of the symplectic form vanishes. In particular\, the conjecture asserts that all such submanifolds are diffeomorphic. In view of recent work with Alvarez-Gavela\, Courte\, and Kragh\, as well as work of Procelli and Smith\, I will use the question as a motivation for joint work with Andrew Blumberg on a bordism-theoretic approach to define bordism-valued refinements of Floer homology. \n  \nSeptember 17\, 2026 \nTitle: Complex bordism and Hamiltonian fibrations \nAbstract: As a consequence of his theory of weights\, Deligne proved that smooth complex projective varieties\, carrying a smooth morphism to the projective line\, have rational cohomology groups that are isomorphic to the tensor product of the cohomology of the fibre with that of the base. In joint work with McLean and Smith\, we should that the result not only holds for symplectic manifolds\, but is in fact a consequence of an analogous result that holds for complex cobordism. The proof identifies bordism of “stably complex derived orbifolds” as the correct framework in which to formulate these results\, and I will discuss joint work with Shaoyun Bai to understand these bordism groups. \nThe Ahlfors Lecture Series is presented by the Harvard University Math Department in memory of  Professor Lars Ahlfors.

SUMMARY:CMSA Special Lecture: New Math + AI Developments in Fluid Mechanics
DESCRIPTION:CMSA Special Lecture\nTime: 2:30 pm ET\nDate: Friday\, Sep. 11\, 2026\nLocation: Harvard Science Center Hall A & via Zoom Webinar \n  \nLecture Video \n \n  \nWith the announcement this week that AI has finished off a solution to one of the Millennium Prize Problems\, the Harvard CMSA will host this special lecture to review recent developments on the existence and smoothness of solutions to the Navier–Stokes equation. \n  \nSpeaker: Javier Gomez-Serrano\, Brown University \nTitle: New Math + AI Developments in Fluid Mechanics \nAbstract: In this talk I will discuss recent progress on finite-time singularity formation for several fluid equations\, from model problems to the Navier–Stokes and Euler systems themselves. I will put this progress in context and close with the recently announced resolution of the Navier–Stokes existence and smoothness problem\, via an explicit construction exhibiting finite-time blow-up from smooth data alongside closely related\, independently obtained blow-up results for forced Euler. Both rely on an AI-assisted proof search\, marking a new mode of mathematical discovery for problems of this depth. \n  \nThis lecture will be given in person in Science Center Lecture Hall A\, 1 Oxford Street\, Cambridge MA & via Zoom Webinar (registration required). \nZoom Webinar Registration

SUMMARY:Sixth Annual Yip Lecture | Regina Barzilay\, MIT: Can machine learning methods design drugs?
DESCRIPTION:Sixth Annual Yip Lecture \nDate: April 23\, 2026 \nTime: 4:00–5:00 pm ET \nLocation: Harvard Science Center Hall A & via Zoom Webinar \nSpeaker: Regina Barzilay\, MIT \nTitle: Can ML methods design drugs? \nAbstract: Today\, life sciences are driven by prohibitively expensive wet lab experimentations\, which limit the pace and scope of discovery. This talk focuses on AI algorithms that enable in-silico modeling of biological processes. Specifically\, I will focus on algorithms for molecular and cellular modeling. I will highlight several successful examples where these algorithms have already transformed drug discovery. In the second part of the talk\, I want to focus on problems where current methods fail to deliver as expected\, motivating the need for algorithmic innovations. \nBio: Regina Barzilay is a School of Engineering Distinguished Professor for AI and Health in the Department of Electrical Engineering and Computer Science (EECS) at MIT. Since 2018\, she has been the AI faculty lead for the MIT Jameel Clinic and a member of MIT CSAIL. \nShe is a member of three national academies\, including the National Academy of Engineering\, the National Academy of Medicine\, and the American Academy of Arts & Sciences. \nShe is also a recipient of various awards\, including a 2017 MacArthur fellowship “Genius Grant.” In 2020\, she was awarded the Squirrel AI Award for Artificial Intelligence for the Benefit of Humanity. More recently\, she has been recognized in the 2025 TIME100 AI List and awarded with the IEEE Frances E. Allen Medal for her development of innovative machine learning algorithms that have significantly advanced human language technology and transformed medical diagnostics and drug discovery. \nShe completed her PhD in Computer Science from Columbia University\, and spent a year as a postdoc at Cornell University.

SUMMARY:CMSA/Tsinghua Math-Science Literature Lecture: Nicolai Reshetikhin (Tsinghua): Asymptotic representation theory
DESCRIPTION:CMSA/Tsinghua Math-Science Literature Lecture \nDate: April 22\, 2026 \nTime: 9:00 – 10:30 am ET \nLocation: via Zoom Webinar \nSpeaker: Nicolai Reshetikhin\, Yau Mathematical Sciences Center\, Tsinghua University \nTitle: Asymptotic representation theory \nAbstract: Loosely speaking asymptotic representation theory studies representations of “large” groups or algebras. One of the first results in this direction is the study of Plancherel measures on the symmetric group $S_N$ in the limit $N\to \infty$ by Vershik and Kerov and Logan and Shepp. The first part of the talk will be an overview of results on statistics of irreducible representations in large tensor products. Then we focus on more modern results on statistics of tilting and projective modules in large tensor products and on how some problems in asymptotic representation theory are related to dimer models in statistical mechanics. \n\nBeginning in Spring 2020\, the CMSA began hosting a lecture series on literature in the mathematical sciences\, with a focus on significant developments in mathematics that have influenced the discipline\, and the lifetime accomplishments of significant scholars. \n  \n

SUMMARY:Millennium Prize Problems Lecture - Javier Gómez-Serrano: Navier-Stokes Existence or Breakdown
DESCRIPTION:Date: March 11\, 2026 \nTime: 5:00–6:00 pm \nLocation: Harvard Science Center Hall C\, 1 Oxford St.\, Cambridge MA & via Zoom Webinar \nSpeaker: Javier Gómez-Serrano\, Brown University \nTitle: Navier-Stokes Existence or Breakdown \nAbstract: The Navier-Stokes equations have been the cornerstone of fluid dynamics for over a century\, accurately describing the motion of viscous fluids such as water and air. However\, despite their fundamental importance to mathematics and physics\, a profound question remains unanswered: do solutions to these equations always exist for all time\, or can they break down and develop singularities (points where the equations lose their validity)? In this Millennium Prize Problems Lecture\, I will explore the current mathematical landscape surrounding the Navier-Stokes and related equations. The talk will discuss the historical context\, the ongoing search for global regularity versus finite-time blowup\, and the latest analytical and computational breakthroughs pushing the boundaries of what we know about fluid behavior. \nRead more about the Navier-Stokes Equation at the Clay Math website. \n  \nOrganizers: Martin Bridson\, Clay Mathematics Institute | Dan Freed\, Harvard University and CMSA | Mike Hopkins\, Harvard University \n\n                   \n\nMillennium Prize Problems Lecture Series

SUMMARY:CMSA/Tsinghua Math-Science Literature Lecture: Martin Bridson: Profinite rigidity: Chasing finite shadows of infinite groups
DESCRIPTION:CMSA/Tsinghua Math-Science Literature Lecture \n \nDate: March 10\, 2026 \nTime: 8:45 – 10:15 am ET \nLocation: Harvard Science Center Hall A\, 1 Oxford Street\, Cambridge MA &  via Zoom Webinar \nSpeaker: Martin Bridson FRS is the Whitehead Professor of Pure Mathematics at Oxford and President of the Clay Mathematics Institute. \nTitle: Profinite rigidity: Chasing finite shadows of infinite groups \nAbstract: There are many situations in geometry or elsewhere in mathematics where it is natural or convenient to explore infinite groups of symmetries via their actions on finite objects. But how hard is it to find these finite manifestations and to what extent does the collection of all such actions determine the infinite group?\nIn this talk\, I will sketch some of the rich history of such problems and then describe some of the significant advances in recent years. \nWe’ll pay particular attention to groups that arise in 3-dimensional geometry and topology. \n  \n\nBeginning in Spring 2020\, the CMSA began hosting a lecture series on literature in the mathematical sciences\, with a focus on significant developments in mathematics that have influenced the discipline\, and the lifetime accomplishments of significant scholars. \n  \n

SUMMARY:2026 Ding Shum Lecture: Sanjeev Arora\, Princeton
DESCRIPTION:2026 Ding Shum Lecture \nDate: March 4\, 2026 \nTime: 4:00 pm \nLocation: Harvard Science Center Hall D & via Zoom Webinar \nSpeaker: Sanjeev Arora\, Princeton \nTitle: How could a Superhuman AI mathematician come about? \n\nAbstract: Can AI systems exceed the capabilities of the human experts who provided their training data? The talk will examine the hypothesis of AI self‑improvement\, involving mechanisms such as synthetic data generation\, reinforcement learning\, and tool‑augmented reasoning with formal verification loops. \nI will also present recent work at Princeton\, including the Gödel Prover V2 for Lean‑based theorem proving and a new inference pipeline that achieved state‑of‑the‑art performance (at the time of evaluation) on IMO‑ProofBench (Advanced) at moderate inference costs ($20–$30 per problem). These will illustrate how AI systems are sometimes able to escape “cognitive wells”—local optima in a model’s reasoning capabilities. While providing evidence for the feasibility of self‑improvement\, they also highlight important hurdles and open questions. \n\n  \n\n \nSanjeev Arora is Charles C. Fitzmorris Professor of Computer Science and Director of Princeton Language and Intelligence\, a unit devoted to research and applications of large AI models. He got his Phd from UC Berkeley in 1994 and has been a faculty member at Princeton since then. He has been awarded the ACM Prize in Computing (2011)\, Fulkerson Prize in Discrete Mathematics (2012)\, Packard Fellowship\, Sloan Fellowship\, and the ACM Doctoral Dissertation Prize. He was a plenary speaker at the International Congress of Mathematicians in 2018 and is a member of the National Academy of Science and American Academy of Arts and Sciences. \n\n\n\n\n\nThis event is made possible by the generous funding of Ding Lei and Harry Shum.\n\n\n

SUMMARY:Millennium Prize Problems Lecture - Barry Mazur: About the Birch and Swinnerton–Dyer Conjecture
DESCRIPTION:Date: February 4\, 2026 \nTime: 5:00–6:00 pm \nLocation: Harvard Science Center Hall C\, 1 Oxford St.\, Cambridge MA \nSpeaker: Barry Mazur\, Harvard University \nTitle: About the Birch and Swinnerton–Dyer Conjecture \nAbstract: \nIn the 1950s Bryan Birch and Peter Swinnerton–Dyer made computations that suggested a striking connection between a basic global invariant of an elliptic curve E over the field of rational numbers (namely\, the rank of its group of rational points) and certain asymptotics of its local arithmetic invariants (i.e.\, the number of its rational points over finite fields). \nThis initial observation has evolved into their conjecture. My lecture will be an introduction to the general ideas behind its ever-expanding development. \nRead more about the Birch and Swinnerton–Dyer Conjecture at the Clay Math website. \n  \nOrganizers: Martin Bridson\, Clay Mathematics Institute | Dan Freed\, Harvard University and CMSA | Mike Hopkins\, Harvard University \nBarry Mazur joined the Harvard University faculty in 1959 as a Junior Fellow in the Society of Fellows and advanced through the ranks to become the Gerhard Gade University Professor of Mathematics\, a position he has held since 1998. During his tenure at Harvard\, he has mentored 60 doctoral students and served as a pivotal figure in bridging topology and number theory\, notably through his classification of the possible torsion subgroups of elliptic curves over the rational numbers (Mazur’s torsion theorem)\, which identifies exactly 15 possible finite groups. This theorem\, detailed in his 1977 paper “Modular curves and the Eisenstein ideal\,” provided crucial insights into the Taniyama-Shimura conjecture and laid groundwork for Andrew Wiles’s 1994 proof of Fermat’s Last Theorem. \nHis broader research includes seminal works on étale homotopy theory (co-authored with Michael Artin in 1969)\, the arithmetic moduli of elliptic curves (with Nicholas M. Katz in 1985)\, and the Iwasawa main conjecture (proved with Andrew Wiles in 1984)\, as well as advancements in p-adic L-functions and the formulation of the Fontaine-Mazur conjecture on Galois representations. Mazur’s influence extends to public communication of mathematics; he has authored books like Imagining Numbers (2003)\, exploring historical perspectives on complex numbers. \nAmong his numerous honors\, Mazur received the Cole Prize in Number Theory from the American Mathematical Society in 1982\, the Chauvenet Prize in 1994 for expository writing\, the Leroy P. Steele Prize for Lifetime Achievement in 2000\, and election to the National Academy of Sciences in 1982. In 2011 (presented in 2013)\, he was awarded the National Medal of Science by President Barack Obama for his pioneering work in these fields.Most recently\, in 2022\, he received the Chern Medal from the International Mathematical Union\, recognizing his profound discoveries and mentorship. \n  \n\n                   \n\nMillennium Prize Problems Lecture Series \n

SUMMARY:Millennium Prize Problems Lecture - Madhu Sudan: P vs NP Problem
DESCRIPTION:Pamphlet (pdf) \nSlides (pdf) \nDate: December 3\, 2025 \nTime: 5:00–6:00 pm \nLocation: Harvard Science Center Hall D\, 1 Oxford St.\, Cambridge MA \nSpeaker: Madhu Sudan\, Harvard University \nTitle: The P vs. NP problem: An Existential Question for Mathematics \nAt the beginning of the twentieth century\, in response to questions raised by Hilbert\, illustrious mathematicians such as Godel\, Church and Turing formalized the notion of theorems and proofs. Proofs were automatically verifiable while theorems are logical propositions for which proofs exist. The formal definition of a computer\, a definition that had strong influence on the later development of the technology\, was a by-product of the effort to define the phrase “automatically verifiable”! \nWhile the resulting theory had major implications already\, one notion was however missing in the early definitions. Proofs were meant to be easily verifiable\, while determining the truth of a proposition/conjecture (arguably a core task of mathematics) was not necessarily so. But what is “easiness” and how is it to be defined? While this was already hinted at by Godel in the 50s\, the notion was finally formalized in seminal works of Cook\, Levin and Karp in the early 70s. Central notions here included the adoption of the notion that polynomial time algorithms are (the only) tractable ones\, and the realization that algorithms seeking to remove the existential quantifier in the definition of a “theorem” lead naively to exponential time algorithms. But are there no sophisticated algorithms to search for proofs? This is the profound “Is P = NP?” question. \nIn this talk we will introduce the question and explain implications of resolutions of this question to the modern computing infrastructure\, to mathematics and other sciences. We will briefly describe the state of progress on this question and recent progress on weaker forms of this question. Finally we will also aim to connect this question\, and why one may believe that P != NP (proof search can not be automated) even in the face of accumulating evidence on the ability of computers to solve more and more complex mathematical problems\, which seem to implement brute force search in less than polynomial time. \n  \nRead more about the P vs NP Problem at the Clay Math website. \n  \nOrganizers: Martin Bridson\, Clay Mathematics Institute | Dan Freed\, Harvard University and CMSA | Mike Hopkins\, Harvard University \n\n                   \n\nMillennium Prize Problems Lecture Series

SUMMARY:Millennium Prize Problems Lecture - Sourav Chatterjee: Yang-Mills and the foundations of quantum field theory
DESCRIPTION:Millennium Prize Problems Lecture  \nDate: October 15\, 2025 \nTime: 5:00–6:00 pm \nLocation: Harvard Science Center Hall D\, 1 Oxford St.\, Cambridge MA \nSpeaker: Sourav Chatterjee\, Stanford University \nTitle: Yang-Mills and the foundations of quantum field theory \nAbstract: Yang-Mills theories are the building blocks of the Standard Model of quantum mechanics\, which is the best available model for our universe at the quantum scale. Yet\, these theories do not have a rigorous mathematical foundation. Physical calculations are based on perturbation theory\, but there are various phenomena that are believed to be out of the reach of perturbative arguments. Building a mathematical foundation is\, therefore\, important even from the physics point of view. A program with this objective\, known as “constructive field theory”\, was initiated in the 1960s. In spite of many successes\, the program has not reached its original goal. Completing this program is the Clay Millennium Prize problem of Yang-Mills existence and mass gap. I will give a general introduction to the main questions\, and an overview of exciting recent progress that has rejuvenated the quest for a solution in the last ten years. \nRead more about the Yang-Mills Existence and Mass Gap at the Clay Math website. \nOrganizers: Martin Bridson\, Clay Mathematics Institute | Dan Freed\, Harvard University and CMSA | Mike Hopkins\, Harvard University \n\n                   \n\nMillennium Prize Problems Lecture Series

SUMMARY:Millennium Prize Problems Lecture - Michael Freedman: The Poincaré Conjecture and Mathematical Discovery  
DESCRIPTION:Millennium Prize Problems Lecture\nDate: September 17\, 2025 \nLocation: Harvard Science Center Hall D & via Zoom Webinar \nTime: 5:00–6:00 pm \nSpeaker: Michael Freedman\, Harvard CMSA and Logical Intelligence  \nTitle: The Poincaré Conjecture and Mathematical Discovery   \nAbstract: The AI age requires us to re-examine what mathematics is about. The Seven Millenium Problems provide an ideal lens for doing so. Five of the seven are core mathematical questions\, two are meta-mathematical – asking about the scope of mathematics. The Poincare conjecture represents one of the core subjects\, manifold topology. I’ll explain what it is about\, its broader context\, and why people cared so much about finding a solution\, which ultimately arrived through the work of R. Hamilton and G. Perelman. Although stated in manifold topology\, the proof requires vast developments in the theory of parabolic partial differential equations\, some of which I will sketch. Like most powerful techniques\, the methods survive their original objectives and are now deployed widely in both three- and four-dimensional manifold topology.  \n  \nRead more about the Poincaré Conjecture at the Clay Math website. \nOrganizers: Martin Bridson\, Clay Mathematics Institute | Dan Freed\, Harvard University and CMSA | Mike Hopkins\, Harvard University \n\n                   \n\nMillennium Prize Problems Lecture Series

SUMMARY:Fifth Annual Yip Lecture | Scott Aaronson (UT Austin): How Much Math Is Knowable?
DESCRIPTION:Speaker: Scott Aaronson\, Department of Computer Science\, University of Texas\, Austin \nScott Aaronson is the founding director at the Quantum Information Center at the University of Texas at Austin. \nDate: April 17\, 2025 \nTime: 4:00-5:00 pm ET  (Reception following in the Math Common Room) \nLocation: Harvard Science Center Hall A \n  \nTitle: How Much Math Is Knowable? \nAbstract: Theoretical computer science has over the years sought more and more refined answers to the question of which mathematical truths are knowable by finite beings like ourselves\, bounded in time and space and subject to physical laws.  I’ll tell a story that starts with Gödel’s Incompleteness Theorem and Turing’s discovery of uncomputability.  I’ll then introduce the spectacular Busy Beaver function\, which grows faster than any computable function.  Work by me and Yedidia\, along with recent improvements by O’Rear and Riebel\, has shown that the value of BB(745) is independent of the axioms of set theory; on the other end\, an international collaboration proved last year that BB(5) = 47\,176\,870.  I’ll speculate on whether BB(6) will ever be known\, by us or our AI successors.  I’ll next discuss the P!=NP conjecture and what it does and doesn’t mean for the limits of machine intelligence.  As my own specialty is quantum computing\, I’ll summarize what we know about how scalable quantum computers\, assuming we get them\, will expand the boundary of what’s mathematically knowable.  I’ll end by talking about hypothetical models even beyond quantum computers\, which might expand the boundary of knowability still further\, if one is able (for example) to jump into a black hole\, create a closed timelike curve\, or project oneself onto the holographic boundary of the universe. \n  \nThe Yip Lecture takes place thanks to the support of Dr. Shing-Yiu Yip. \n  \n\nThe previous Yip Lecture featured Josh Tenenbaum (MIT) who spoke on How to grow a mind from a brain: From guessing and betting to thinking and talking \n

SUMMARY:CMSA/Tsinghua Math-Science Literature Lecture: Scott Sheffield (MIT): Yang-Mills theory and random surfaces
DESCRIPTION:CMSA/Tsinghua Math-Science Literature Lecture \nDate: April 8\, 2025 \nTime: 9:00 – 10:30 am ET \nLocation: CMSA G10\, 20 Garden Street\, Cambridge MA & via Zoom \nSpeaker: Scott Sheffield (MIT) \nTitle: Yang-Mills theory and random surfaces \nAbstract: The Clay Institute famously offered one million dollars to anyone who could mathematically construct and understand a certain continuum version of “Yang-Mills gauge theory.” This theory is the basis of the standard model of physics\, and the heart of the problem is to understand the so-called “Wilson loop expectations.” Following recent work with Sky Cao and Minjae Park\, I will explain how the “Wilson loop expectations” in a lattice Yang-Mills model are equivalent to “insertion costs” of loops in a related random-closed-surface-ensemble model. In a sense\, these results allow us to convert one famously hard problem into another presumably hard problem. But the new problem is all about random surfaces and random permutations\, and it has a lot of relationships with and similarities to other problems we understand (think domino tilings\, random planar maps\, Young tableaux and symmetric group representation theory\, and the Weingarten calculus). It gives us some intuition for *why* certain things should be true like the “area law” or “exponential correlation decay” (what physicists call “quark confinement” or “mass gap”) even if we can’t prove all of them yet. \n\nBeginning in Spring 2020\, the CMSA began hosting a lecture series on literature in the mathematical sciences\, with a focus on significant developments in mathematics that have influenced the discipline\, and the lifetime accomplishments of significant scholars.

SUMMARY:2025 Ding Shum Lecture: Irit Dinur\, IAS: Expanders from local to global
DESCRIPTION:  \n \nOn February 13\, 2025 the CMSA hosted the sixth annual Ding Shum Lecture\, given by Irit Dinur\, Institute for Advanced Study. \nLocation: Harvard Science Center  Hall A & via Zoom Webinar \nSpeaker: Irit Dinur\, Institute for Advanced Study \n\n\n\nTitle: Expanders from local to global \nAbstract: Imagine a network—like a social network\, a transportation system\, or even a biological system—where every part of the network is robustly connected to the rest. Expander graphs are the mathematical idealization of such networks. They are structures where any small group of points (nodes) has many connections to the rest of the graph\, ensuring that no part is isolated and information (or influence) spreads efficiently throughout.\nWe will begin by surveying expander graphs\, their discovery and construction\, and some fascinating applications such as error-correcting codes\, pseudorandomness\, and probabilistically checkable proofs (PCPs)\, highlighting their role as a foundation for many breakthroughs in theoretical computer science. Then\, we will shift focus to an exciting new kind of expanders called high dimensional expanders (HDXs). While expanders are well-understood and widely applied\, HDXs remain enigmatic\, with potential that we are only starting to uncover. We will talk about a fascinating local to global feature that HDXs have\, and some applications. \n\n \n\n\n\n\nThis event is made possible by the generous funding of Ding Lei and Harry Shum.\n\n\n

SUMMARY:Math Science Lectures in Honor of Raoul Bott: Andrew Neitzke
DESCRIPTION:Speaker: Andrew Neitzke\, Yale University \nLocation: Harvard University Science Center Hall D & via Zoom webinar \nDates: October 16 & 17\, 2024 \nTime: 4:00 pm \n  \n \nWednesday\, Oct. 16\, 2024 \nTitle: Abelianization in analysis of ODEs \nAbstract: I will describe the exact WKB method for asymptotic analysis of families of ODEs in one variable\, and its interpretation as a kind of abelianization procedure\, which replaces GL(N)-connections over a Riemann surface by GL(1)-connections over an N-fold branched cover. This abelianization procedure connects exact WKB to various subjects in geometry (cluster algebras\, moduli of Higgs bundles\, enumerative geometry).

The aim is to explain how abelianization gives a unifying perspective on constructions familiar in each of these subjects (e.g. dilogarithmic formulas for Chern-Simons invariants\, vertex models for computing quantum invariants of links\, and iterated-fusion constructions of conformal blocks for the Virasoro algebra)\, and also suggests various extensions\, which are just beginning to be explored. \n\n  \nRaoul Bott (9/24/1923 – 12/20/2005) is known for the Bott periodicity theorem\, the Morse–Bott functions\, and the Borel–Bott–Weil theorem.

SUMMARY:CMSA/Tsinghua Math-Science Literature Lecture: Marc Lackenby
DESCRIPTION:CMSA/Tsinghua Math-Science Literature Lecture \nDate: Wednesday\, September 18\, 2024 \nTime: 9:00 – 10:30 am ET \nLocation: Via Zoom Webinar \nSpeaker: Marc Lackenby\, University of Oxford \nTitle: The complexity of knots \nAbstract: In his final paper in 1954\, Alan Turing wrote `No systematic method is yet known by which one can tell whether two knots are the same.’ Within the next 20 years\, Wolfgang Haken and Geoffrey Hemion had discovered such a method. However\, the computational complexity of this problem remains unknown. In my talk\, I will give a survey on this area\, that draws on the work of many low-dimensional topologists and geometers. Unfortunately\, the current upper bounds on the computational complexity of the knot equivalence problem remain quite poor. However\, there are some recent results indicating that\, perhaps\, knots are more tractable than they first seem. Specifically\, I will explain a theorem that provides\, for each knot type K\, a polynomial p_K with the property that any two diagrams of K with n_1 and n_2 crossings differ by at most p_K(n_1) + p_K(n_2) Reidemeister moves. \n\nBeginning in Spring 2020\, the CMSA began hosting a lecture series on literature in the mathematical sciences\, with a focus on significant developments in mathematics that have influenced the discipline\, and the lifetime accomplishments of significant scholars.

SUMMARY:2024 Ding Shum Lecture: Yann LeCun: Objective-Driven AI: Towards AI systems that can learn\, remember\, reason\, and plan
DESCRIPTION:LECTURE SLIDES (pdf) \nOn March 28\, 2024\, the CMSA will host the fifth annual Ding Shum Lecture\, given by Yann LeCun. \nTime: 4:30–5:30 pm ET \nSpeaker: Yann Lecun\, New York University & META \nLocation: Harvard Science Center  Hall A & via Zoom Webinar \nTitle: Objective-Driven AI: Towards AI systems that can learn\, remember\, reason\, and plan \n\n\nAbstract:  \nHow could machines learn as efficiently as humans and animals? \nHow could machines learn how the world works and acquire common sense? \nHow could machines learn to reason and plan? \nCurrent AI architectures\, such as Auto-Regressive Large Language Models fall short. I will propose a modular cognitive architecture that may constitute a path towards answering these questions. The centerpiece of the architecture is a predictive world model that allows the system to predict the consequences of its actions and to plan a sequence of actions that optimize a set of objectives. The objectives include guardrails that guarantee the system’s controllability and safety. The world model employs a Hierarchical Joint Embedding Predictive Architecture (H-JEPA) trained with self-supervised learning. The JEPA learns abstract representations of the percepts that are simultaneously maximally informative and maximally predictable. The corresponding working paper is available here: https://openreview.net/forum?id=BZ5a1r-kVsf \n\n\n\n\n\n\n\n\n\n\nThis event is made possible by the generous funding of Ding Lei and Harry Shum. \n

SUMMARY:Math Science Lectures in Honor of Raoul Bott: Maggie Miller: Fibered ribbon knots vs. major 4D conjectures
DESCRIPTION:Fibered ribbon knots vs. major 4D conjectures \nLocation: Harvard University Science Center Hall A & via Zoom webinar \nDates: Feb 20 & 22\, 2024 \nTime: 4:00-5:30 pm \nMaggie Miller is an assistant professor in the mathematics department at the University of Texas at Austin and a Clay Research Fellow. \nThis is the fourth annual Math Science Lecture Series held in Honor of Raoul Bott. \nTalk topic:  Fibered ribbon knots vs. major 4D conjectures\n  \n \nFeb. 20\, 2024 \nTitle: Fibered ribbon knots and the Poincaré conjecture \nAbstract: A knot is “fibered” if its complement in S^3 is the total space of a bundle over the circle\, and ribbon if it bounds a smooth disk into B^4 with no local maxima with respect to radial height. A theorem of Casson-Gordon from 1983 implies that if a fibered ribbon knot does not bound any fibered disk in B^4\, then the smooth 4D Poincaré conjecture is false. I’ll show that unfortunately (?) many ribbon disks bounded by fibered knots are fibered\, giving some criteria for extending fibrations and discuss how one might search for non-fibered examples. \n  \n \nFeb. 22\, 2024 \nTitle: Fibered knots and the slice-ribbon conjecture \nAbstract: The slice-ribbon conjecture (Fox\, 1962) posits that if a knot bounds any smooth disk into B^4\, it also bounds a ribbon disk. The previously discussed work of Casson-Gordon yields an obstruction to many fibered knots being ribbon\, yielding many interesting potential counterexamples to this conjecture — if any happy to bound a non-ribbon disk. In 2022\, Dai-Kong-Mallick-Park-Stoffregen showed that unfortunately( ?) many of these knots don’t bound a smooth disk into B^4 and thus can’t disprove the conjecture. I’ll show a simple alternate proof that a certain interesting knot (the (2\,1)-cable of the figure eight) isn’t slice and discuss remaining open questions. This talk is joint with Paolo Aceto\, Nickolas Castro\, JungHwan Park\, and Andras Stipsicz. \n  \nTalk Chair: Cliff Taubes (Harvard Mathematics) \nModerator: Freid Tong (Harvard CMSA) \n\nRaoul Bott (9/24/1923 – 12/20/2005) is known for the Bott periodicity theorem\, the Morse–Bott functions\, and the Borel–Bott–Weil theorem.
