SUMMARY:CMSA Math-Science Literature Lecture: Classical and quantum integrable systems in enumerative geometry
DESCRIPTION:Andrei Okounkov (Columbia University) \nTitle: Classical and quantum integrable systems in enumerative geometry \nAbstract: For more than a quarter of a century\, thanks to the ideas and questions originating in modern high-energy physics\, there has been a very fruitful interplay between enumerative geometry and integrable system\, both classical and quantum. While it is impossible to summarize even the most important aspects of this interplay in one talk\, I will try to highlight a few logical points with the goal to explain the place and the role of certain more recent developments. \nTalk chair: Cumrun Vafa \nVideo

SUMMARY:CMSA Math-Science Literature Lecture: Kunihiko Kodaira and complex manifolds
DESCRIPTION:Yujiro Kawamata (University of Tokyo) \nTitle: Kunihiko Kodaira and complex manifolds \nAbstract: Kodaira’s motivation was to generalize the theory of Riemann surfaces in Weyl’s book to higher dimensions.  After quickly recalling the chronology of Kodaira\, I will review some of Kodaira’s works in three sections on topics of harmonic analysis\, deformation theory and compact complex surfaces.  Each topic corresponds to a volume of Kodaira’s collected works in three volumes\, of which I will cover only tiny parts. \nTalk chair: Baohua Fu \nVideo

SUMMARY:CMSA Math-Science Literature Lecture: Immersions of manifolds and homotopy theory
DESCRIPTION:Ralph Cohen (Stanford University) \nTitle: Immersions of manifolds and homotopy theory \nAbstract: The interface between the study of the topology of differentiable manifolds and algebraic topology has been one of the richest areas of work in topology since the 1950’s. In this talk I will focus on one aspect of that interface: the problem of studying embeddings and immersions of manifolds using homotopy theoretic techniques. I will discuss the history of this problem\, going back to the pioneering work of Whitney\, Thom\, Pontrjagin\, Wu\, Smale\, Hirsch\, and others. I will discuss the historical applications of this homotopy theoretic perspective\, going back to Smale’s eversion of the 2-sphere in 3-space. I will then focus on the problems of finding the smallest dimension Euclidean space into which every n-manifold embeds or immerses. The embedding question is still very much unsolved\, and the immersion question was solved in the 1980’s. I will discuss the homotopy theoretic techniques involved in the solution of this problem\, and contributions in the 60’s\, 70’s and 80’s of Massey\, Brown\, Peterson\, and myself. I will also discuss questions regarding the best embedding and immersion dimensions of specific manifolds\, such has projective spaces. Finally\, I will end by discussing more modern approaches to studying spaces of embeddings due to Goodwillie\, Weiss\, and others. This talk will be geared toward a general mathematical audience. \nTalk chair: Michael Hopkins \nVideo

SUMMARY:CMSA Math-Science Literature Lecture: A personal story of the 4D Poincare conjecture
DESCRIPTION:Michael Freedman (Microsoft – Station Q) \nTitle: A personal story of the 4D Poincare conjecture \nAbstract:  The proof of PC4 involved the convergence of several historical streams.  To get started: high dimensional manifold topology (Smale)\, a new idea on how to study 4-manifolds (Casson)\, wild “Texas” topology (Bing). Once inside the proof: there are three submodules: Casson towers come to life (in the sense of reproduction)\, a very intricate explicit shrinking argument (provided by Edwards)\, and the “blind fold” shrinking argument (which in retrospect is in the linage of Brown’s proof of the Schoenflies theorem). Beyond those mentioned: Kirby\, Cannon\, Ancel\, Quinn\, and Starbird helped me understand my proof. I will discuss the main points and how they fit together. \nTalk Chair: Peter Kronheimer \nVideo

SUMMARY:CMSA Math-Science Literature Lecture: From Deep Learning to Deep Understanding
DESCRIPTION:Harry Shum (Tsinghua University) \nTitle: From Deep Learning to Deep Understanding \nAbstract: In this talk I will discuss a couple of research directions for robust AI beyond deep neural networks. The first is the need to understand what we are learning\, by shifting the focus from targeting effects to understanding causes. The second is the need for a hybrid neural/symbolic approach that leverages both commonsense knowledge and massive amount of data. Specifically\, as an example\, I will present some latest work at Microsoft Research on building a pre-trained grounded text generator for task-oriented dialog. It is a hybrid architecture that employs a large-scale Transformer-based deep learning model\,  and symbol manipulation modules such as business databases\, knowledge graphs and commonsense rules. Unlike GPT or similar language models learnt from data\, it is a multi-turn decision making system which takes user input\, updates the belief state\, retrieved from the database via symbolic reasoning\, and decides how to complete the task with grounded response. \nTalk chair: Shing-Tung Yau \nVideo

SUMMARY:CMSA Math-Science Literature Lecture: Area-minimizing integral currents and their regularity
DESCRIPTION:Camillo De Lellis (IAS) \nTitle: Area-minimizing integral currents and their regularity \nAbstract: Caccioppoli sets and integral currents (their generalization in higher codimension) were introduced in the late fifties and early sixties to give a general geometric approach to the existence of area-minimizing oriented surfaces spanning a given contour. These concepts started a whole new subject which has had tremendous impacts in several areas of mathematics: superficially through direct applications of the main theorems\, but more deeply because of the techniques which have been invented to deal with related analytical and geometrical challenges. In this lecture I will review the basic concepts\, the related existence theory of solutions of the Plateau problem\, and what is known about their regularity. I will also touch upon several fundamental open problems which still defy our understanding.  \nTalk Chair: William Minicozzi \nVideo

SUMMARY:CMSA Math-Science Literature Lecture: My life and times with the sporadic simple groups
DESCRIPTION:Robert Griess (University of Michigan) \nTitle: My life and times with the sporadic simple groups \nAbstract: Five sporadic simple groups were proposed in 19th century and 21 additional ones arose during the period 1965-1975. There were many discussions about the nature of finite simple groups and how sporadic groups are placed in mathematics. While in mathematics grad school at University of Chicago\,  I became fascinated with the unfolding story of sporadic simple groups. It involved theory\, detective work and experiments. During this lecture\, I will describe some of the people\, important ideas and evolution of thinking about sporadic simple groups. Most should be accessible to a general mathematical audience. \nVideo | Slides

SUMMARY:CMSA Math-Science Literature Lecture:  Rationality questions in algebraic geometry
DESCRIPTION:Joe Harris (Harvard) \nTitle: Rationality questions in algebraic geometry \nAbstract: Over the course of the history of algebraic geometry\, rationality questions — motivated by both geometric and arithmetic problems — have often driven the subject forward. The rationality or irrationality of cubic hypersurfaces in particular have led to the development of abelian integrals (dimension one)\, birational geometry (dimension two) and Hodge theory (dimension 3). But there remained much we didn’t understand about the condition of rationality\, such as how it behaves in families. However\, there has been recent progress: work of Hassett\, Tschinkel\, Pirutka and others\, working with examples in dimension 4\, showed that it is in general neither an open condition nor a closed one\, but does behave well with respect to specialization. In this talk I’ll try to give an overview of the history of rationality and the current state of our knowledge. \nVideo

SUMMARY:Frontiers in Applied Mathematics and Computation
DESCRIPTION:Together with the School of Engineering and Applied Sciences\, the CMSA will be hosting a lecture series on the Frontiers in Applied Mathematics and Computation. Talks in this series will aim to highlight current research trends at the interface of applied math and computation and will explore the application of these trends to challenging scientific\, engineering\, and societal problems. \nLectures will take place on March 25\, April 1\, and April 29\, 2021. \nSpeakers: \n\nGeorge Biros (U.T. Austin)\nLaura Grigori (INRIA Paris)\nSamory K. Kpotufe (Columbia)\nJonas Martin Peters (University of Copenhagen)\nJoseph M. Teran (UCLA)\n\n\nThe schedule below will be updated as talks are confirmed. \n  \n\n\n\nDate/Time\nSpeaker\nTitle/Abstract\n\n\n\n\n3/25/2021\n10:00 – 11:00am ET\nJoseph M. Teran\nTitle: Affine-Particle-In-Cell with Conservative Resampling and Implicit Time Stepping for Surface Tension Forces \nAbstract: The Particle-In-Cell (PIC) method of Harlow is one of the first and most widely used numerical methods for Partial Differential Equations (PDE) in computational physics. Its relative efficiency\, versatility and intuitive implementation have made it particularly popular in computational incompressible flow\, plasma physics and large strain elastoplasticity. PIC is characterized by its dual particle/grid (Lagrangian/Eulerian) representation of material where particles are generally used to track material transport in a Lagrangian way and a structured Eulerian grid is used to discretize remaining spatial derivatives in the PDE. I will discuss the importance of conserving linear and angular momentum when switching between these two representations and the recent Affine-Particle-In-Cell (APIC) extension to PIC designed for this conservation. I will also discuss a recent APIC technique for discretizing surface tension forces and their linearizations needed for implicit time stepping. This technique is characterized by a novel surface resampling strategy and I will discuss a generalization of the APIC conservation to this setting.\n\n\n4/1/2021\n9:00 – 10:00am ET\nGeorge Biros\nTitle: Inverse biophysical modeling and its application to neurooncology \nAbstract: A predictive\, patient-specific\, biophysical model of tumor growth would be an invaluable tool for causally connecting diagnostics with predictive medicine. For example\, it could be used for tumor grading\, characterization of the tumor microenvironment\, recurrence prediction\, and treatment planning\,  e.g.\, chemotherapy protocol or enrollment eligibility for clinical trials. Such a model also would provide an important bridge between molecular drivers of tumor growth and imaging-based phenotypic signatures\, and thus\,  help identify and quantify mechanism-based associations between these two. Unfortunately\, such a predictive biophysical model does not exist. Existing models undergoing clinical evaluation are too simple–they do not even capture the MRI phenotype. Although many highly complex models have been proposed\, the major hurdle in deploying them clinically is their calibration and validation. \nIn this talk\, I will discuss the challenges related to the calibration and validation of biophysical models\, and in particular the mathematical structure of the underlying inverse problems. I will also present a new algorithm that localizes the tumor origin within a few millimeters.\n\n\n4/1/2021\n10:00 – 11:00am ET\nSamory K. Kpotufe\nTitle: From Theory to Clustering \nAbstract: Clustering is a basic problem in data analysis\, consisting of partitioning data into meaningful groups called clusters. Practical clustering procedures tend to meet two criteria: flexibility in the shapes and number of clusters estimated\, and efficient processing. While many practical procedures might meet either of these criteria in different applications\, general guarantees often only hold for theoretical procedures that are hard if not impossible to implement. A main aim is to address this gap.\nWe will discuss two recent approaches that compete with state-of-the-art procedures\, while at the same time relying on rigorous analysis of clustering. The first approach fits within the framework of density-based clustering\, a family of flexible clustering approaches. It builds primarily on theoretical insights on nearest-neighbor graphs\, a geometric data structure shown to encode local information on the data density. The second approach speeds up kernel k-means\, a popular Hilbert space embedding and clustering method. This more efficient approach relies on a new interpretation – and alternative use – of kernel-sketching as a geometry-preserving random projection in Hilbert space.\nFinally\, we will present recent experimental results combining the benefits of both approaches in the IoT application domain.\nThe talk is based on various works with collaborators Sanjoy Dasgupta\, Kamalika Chaudhuri\, Ulrike von Luxburg\, Heinrich Jiang\, Bharath Sriperumbudur\, Kun Yang\, and Nick Feamster.\n\n\n4/29/2021\n12:00 – 1:00pm ET\nJonas Martin Peters\nTitle: Causality and Distribution Generalization \nAbstract: Purely predictive methods do not perform well when the test distribution changes too much from the training distribution. Causal models are known to be stable with respect to distributional shifts such as arbitrarily strong interventions on the covariates\, but do not perform well when the test distribution differs only mildly from the training distribution. We discuss anchor regression\, a framework that provides a trade-off between causal and predictive models. The method poses different (convex and non-convex) optimization problems and relates to methods that are tailored for instrumental variable settings. We show how similar principles can be used for inferring metabolic networks. If time allows\, we discuss extensions to nonlinear models and theoretical limitations of such methodology.\n\n\n4/29/2021\n1:00 – 2:00pm ET\nLaura Grigori\nTitle: Randomization and communication avoiding techniques for large scale linear algebra \nAbstract: In this talk we will discuss recent developments of randomization and communication avoiding techniques for solving large scale linear algebra operations. We will focus in particular on solving linear systems of equations and we will discuss a randomized process for orthogonalizing a set of vectors and its usage in GMRES\, while also exploiting mixed precision.  We will also discuss a robust multilevel preconditioner that allows to further accelerate solving large scale linear systems on parallel computers.

SUMMARY:Math Science Lectures in Honor of Raoul Bott: Mina Aganagic
DESCRIPTION:On April 9 and 10\, 2019 the CMSA hosted two lectures by Mina Aganagic (UC Berkeley).  This was the second annual Math Science Lecture Series held in honor of Raoul Bott. \nThe lectures took place in Science Center\, Hall C \n“Two math lessons from string theory”\n\n\n\n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n \n \nApril 9\, 2019 \nLecture 1 \nTitle: “Lesson on Integrability” \nAbstract: The quantum Knizhnik-Zamolodchikov (qKZ) equation is a difference generalization of the famous Knizhnik-Zamolodchikov (KZ) equation. The problem to explicitly capture the monodromy of the qKZ equation has been open for over 25 years. I will describe the solution to this problem\, discovered jointly with Andrei Okounkov. The solution comes from the geometry of Nakajima quiver varieties and has a string theory origin. \nPart of the interest in the qKZ monodromy problem is that its solution leads to integrable lattice models\, in parallel to how monodromy matrices of the KZ equation lead to knot invariants. Thus\, our solution of the problem leads to a new\, geometric approach\, to integrable lattice models. There are two other approaches to integrable lattice models\, due to Nekrasov and Shatashvili and to Costello\, Witten and Yamazaki. I’ll describe joint work with Nikita Nekrasov which explains how string theory unifies the three approaches to integrable lattice models.\n\n\n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n \n \nApril 10\, 2019 \nLecture 2 \nTitle: “Lesson on Knot Categorification” \nAbstract: An old problem is to find a unified approach to the knot categorification problem. The new string theory perspective on the qKZ equation I described in the first talk can be used to derive two geometric approaches to the problem. \nThe first approach is based on a category of B-type branes on resolutions of slices in affine Grassmannians. The second is based on a category of A-branes in a Landau-Ginzburg theory. The relation between them is two dimensional (equivariant) mirror symmetry. String theory also predicts that a third approach to categorification\, based on counting solutions to five dimensional Haydys-Witten equations\, is equivalent to the first two. \nThis talk is mostly based on joint work with Andrei Okounkov.\n\n\n\n  \n  \n

SUMMARY:2017 Ding Shum Lecture
DESCRIPTION:Leslie Valiant will be giving the inaugural talk of the Ding Shum Lectures on Tuesday\, October 10 at 5:00 pm in Science Center Hall D\, Cambridge\, MA. \nLearning as a Theory of Everything \nAbstract: We start from the hypothesis that all the information that resides in living organisms was initially acquired either through learning by an individual or through evolution. Then any unified theory of evolution and learning should be able to characterize the capabilities that humans and other living organisms can possess or acquire. Characterizing these capabilities would tell us about the nature of humans\, and would also inform us about feasible targets for automation. With this purpose we review some background in the mathematical theory of learning. We go on to explain how Darwinian evolution can be formulated as a form of learning. We observe that our current mathematical understanding of learning is incomplete in certain important directions\, and conclude by indicating one direction in which further progress would likely enable broader phenomena of intelligence and cognition to be realized than is possible at present. \n

SUMMARY:The 2017 Charles River Lectures
DESCRIPTION:Charles River with Bench at Sunset\nJointly organized by Harvard University\, Massachusetts Institute of Technology\, and Microsoft Research New England\, the Charles River Lectures on Probability and Related Topics is a one-day event for the benefit of the greater Boston area mathematics community. \nThe 2017 lectures will take place 9:15am – 5:30pm on Monday\, October 2 at Harvard University  in the Harvard Science Center. \n\n\n\n*************************************************** \nUPDATED LOCATION\nHarvard University\nHarvard Science Center (Halls C & E)\n1 Oxford Street\, Cambridge\, MA 02138 (Map)\nMonday\, October 2\, 2017\n9:15 AM – 5:30 PM\n************************************************** \nPlease note that registration has closed. \nSpeakers:\n\nPaul Bourgade (Courant Institute\, NYU)\nMassimiliano Gubinelli (University of Bonn)\nAndrea Montanari (Stanford University)\nRoman Vershynin (University of California\, Irvine)\nOfer Zeitouni (Weizmann Institute)\n\nAgenda:\nIn Harvard Science Center Hall C: \n8:45 am – 9:15 am: Coffee/light breakfast \n9:15 am – 10:15 am: Ofer Zeitouni \nTitle: Noise stability of the spectrum of large matrices \nAbstract: The spectrum of large non-normal matrices is notoriously sensitive to perturbations\, as the example of nilpotent matrices shows. Remarkably\, the spectrum of these matrices perturbed by polynomially (in the dimension) vanishing additive noise is remarkably stable. I will describe some results and the beginning of a theory. \nThe talk is based on joint work with Anirban Basak and Elliot Paquette\, and earlier works with Feldheim\, Guionnet\, Paquette and Wood.\n\n10:20 am – 11:20 am: Andrea Montanari \nTitle: Algorithms for estimating low-rank matrices  \nAbstract: Many interesting problems in statistics can be formulated as follows. The signal of interest is a large low-rank matrix with additional structure\, and we are given a single noisy view of this matrix. We would like to estimate the low rank signal by taking into account optimally the signal structure. I will discuss two types of efficient estimation procedures based on message-passing algorithms and semidefinite programming relaxations\, with an emphasis on asymptotically exact results. \n11:20 am – 11:45 am: Break \n11:45 am – 12:45 pm: Paul Bourgade \nTitle: Random matrices\, the Riemann zeta function and trees \nAbstract: Fyodorov\, Hiary & Keating have conjectured that the maximum of the characteristic polynomial of random unitary matrices behaves like extremes of log-correlated Gaussian fields. This allowed them to predict the typical size of local maxima of the Riemann zeta function along the critical axis. I will first explain the origins of this conjecture\, and then outline the proof for the leading order of the maximum\, for unitary matrices and the zeta function. This talk is based on joint works with Arguin\, Belius\, Radziwill and Soundararajan. \n1:00 pm – 2:30 pm: Lunch \nIn Harvard Science Center Hall E: \n2:45 pm – 3:45 pm: Roman Vershynin \nTitle: Deviations of random matrices and applications \nAbstract: Uniform laws of large numbers provide theoretical foundations for statistical learning theory. This lecture will focus on quantitative uniform laws of large numbers for random matrices. A range of illustrations will be given in high dimensional geometry and data science. \n3:45 pm – 4:15 pm: Break \n4:15 pm – 5:15 pm: Massimiliano Gubinelli \nTitle: Weak universality and Singular SPDEs \nAbstract: Mesoscopic fluctuations of microscopic (discrete or continuous) dynamics can be described in terms of nonlinear stochastic partial differential equations which are universal: they depend on very few details of the microscopic model. This universality comes at a price: due to the extreme irregular nature of the random field sample paths\, these equations turn out to not be well-posed in any classical analytic sense. I will review recent progress in the mathematical understanding of such singular equations and of their (weak) universality and their relation with the Wilsonian renormalisation group framework of theoretical physics. \nOrganizers:\n Alexei Borodin\, Henry Cohn\, Vadim Gorin\, Elchanan Mossel\, Philippe Rigollet\, Scott Sheffield\, and H.T.
