SUMMARY:A Rigorous Construction of the Free Quantum Field
DESCRIPTION:Joint Math/CMSA Geometry and Quantum Theory Seminar \nSpeaker: Kason Kunkelmann \nTitle: A Rigorous Construction of the Free Quantum Field \nAbstract: In this talk we will build on last week’s discrete intuition and rigorously construct our first continuum quantum field theory: the free field. Following Chapter three of Chatterjee’s notes\, we will realize it as a Gaussian random field in Euclidean spacetime\, prove that it has the Markov property in time\, and then use the procedure outlined in previous lectures to get its Hilbert space and Hamiltonian.

SUMMARY:What is a self-concordant barrier function?\, and what is an accelerated first-order algorithm?  (ICM Series: On the work of Yurii Nesterov)
DESCRIPTION:CMSA Q&A Seminar \nSpeaker: Robert M. Freund\, MIT \nTitle: What is a self-concordant barrier function?\, and what is an accelerated first-order algorithm?  (ICM Series: On the work of Yurii Nesterov) \nAbstract: The two most impactful contributions of Nesterov on both theory and computation in optimization are (i) self-concordant barriers for interior-point methods in convex optimization\, and (ii) accelerated first-order methods for convex optimization. My own research in continuous optimization – and indeed my perspective on the field of mathematical optimization — has been profoundly impacted by Nesterov. In this talk I aim to explain these two contributions – self-concordant barriers and accelerated first-order methods – and how they have fundamentally improved optimization both computationally and theoretically. \n  \n  \n

SUMMARY:Local learning needs dendrites
DESCRIPTION:New Technologies in Mathematics Seminar \nSpeaker: Riccardo Zecchina (Bocconi University) \nTitle: Local learning needs dendrites \nAbstract: I will present a learning scheme for recurrent networks in which nonlinear dendrites enable learning by generating and stabilizing task-relevant attractors within a representation manifold. The scheme is local in space and time and matches the performance of backpropagation through time on the same architecture\, while following a fundamentally different trajectory in weight space. Statistical physics reveals how dendritic gating and the geometry of the representation manifold support this alternative route to learning.

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 \nIn-person registration \nWebinar Registration \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. I’ll explain these conjectures and some progress towards them\, joint with Josh Lam\, for isomonodromy differential equations. This class of differential equations includes\, for example\, the Painlevé VI equation. This work is in part an excuse to study “motivic” aspects of the space of all algebraic differential equations. \n\nThe Monday lecture will be followed by a reception in the Math Dept Austine & Chilton McDonnell Common Room\, 4th floor \n  \nWednesday\, October 21\, 2026 \nLecture 2: Non-abelian motives \nAbstract: Non-abelian Hodge theory\, due to Corlette\, Simpson\, and others\, develops structures on the space of representations of the fundamental group of a complex variety analogous to the structures on its cohomology. Taking this analogy seriously\, we should expect *every* structure on cohomology to have an analogue in this “non-abelian” setting. I’ll discuss some work in this direction\, as well as a number of related conjectures and new structures whose “abelian” analogues are less clear. \n\n  \n\nHarvard Mathematics Professor Raoul Bott (1923 – 2005)\, was a Hungarian-American mathematician known for numerous foundational contributions to geometry in its broad sense. He is best known for his Bott periodicity theorem\, the Morse–Bott functions which he used in this context\, and the Borel–Bott–Weil theorem.

SUMMARY:The Geography of Symplectic 4-Manifolds
DESCRIPTION:Colloquium \nSpeaker: Anar Akhmedov\, University of Minnesota \nTitle: The Geography of Symplectic 4-Manifolds \nAbstract: The symplectic geography problem\, originally posed by J. McCarthy-J. Wolfson and R. Gompf\, asks which ordered pairs of nonnegative integers are realized as (\chi(X)\,c_1^2(X)) for a symplectic 4-manifold X\, where \chi(X)=(e(X)+\sigma(X))/4. In this talk\, we will address the geography of simply connected spin and nonspin symplectic 4-manifolds with small Euler characteristic\, with nonnegative signature\, or near the Bogomolov-Miyaoka-Yau line c_1^2(X)=9\chi_h(X). We will also discuss recent developments\, including joint work with Sai-Kee Yeung on symplectic fake quadrics and related questions motivated by fake projective planes and Cartwright-Steger surfaces. \n  \n\nTo subscribe or unsubscribe to the colloquium mailing list\, please visit this link.

SUMMARY:The IEANTN Project: Automation and Mathematical Understanding
DESCRIPTION:New Technologies in Mathematics Seminar \nSpeaker: Xinjie He\, UCLA \nTitle: The IEANTN Project: Automation and Mathematical Understanding \nAbstract: Explicit analytic number theory combines conceptual arguments with extensive bookkeeping and numerical computation\, often drawing on long chains of results across many papers. The Integrated Explicit Analytic Number Theory Network (IEANTN) aims to organize this literature into a living network whose dependencies and supporting evidence are explicit. \nIn this talk\, I will discuss how we redesigned IEANTN from its 1.0 version\, which put everything in a single Lean repository that was hard to maintain and rebuild as auto-formalization produces increasingly large proofs\, to its current 2.0 version\, which solves this problem by separating readable mathematical statements from verified proofs and recording different levels of justification. \nFinally\, I will discuss what we hope to automate and what we want to understand ourselves. By organizing the literature into a network\, we hope to make the mathematical ideas and relationships easier to see\, and leave the detailed bookkeeping to machines. \n

SUMMARY:Doing Mathematics with AI Agents
DESCRIPTION:Doing Mathematics with AI Agents \nDate: Saturday\, October 31\, 2026 \nTime: 9:00–5:00 pm ET \nLocation:  Zimmer Hall (Science Center)\, 1 Oxford Street\, Cambridge MA \nThis is a one day workshop for Boston-area mathematics faculty to work with AI agents in a collaborative environment (designed by Andrew Sutherland) supported by computational infrastructure and formalization tools. This event is appropriate for: \n\nfaculty who haven’t used AI seriously in their work and want to try\nfaculty who have only worked with AI in chat in a web browser\nfaculty who already use Codex or Claude Code\n\nParticipants will work in a system where they can work with multiple agents\, and do mathematics assisted by AI agents during the day of the workshop. Participants will work with AI agents who are fully set up to do mathematics\, and will talk to other colleagues who are doing the same thing in real time. The landscape of using AI agents in mathematics is changing incredibly quickly. At this workshop\, participants can experiment and learn from others about the possibilities and challenges in what is currently available. \nOnly faculty are eligible for this event. We will hold another workshop on November 21 for postdocs that will have a separate application. \nNo funding is available. We expect participants to be local. \nApply here if you are interested to participate. Space is very limited. Applications will be considered on a rolling basis starting October 21. \nLink to application: https://forms.gle/4beWqoW9VeSCDD3K8 \n  \nOrganizers: Melanie Matchett Wood (Harvard) and Andrew Sutherland (MIT) \n\nThis event is cosponsored by the Harvard Mathematics Department and the CMSA. \n
