A fundamental question at the intersection of Ramsey theory and the theory of random... Read More video lecture Quantum Mechanics, Semidefinite Programming, and Graph Invariants May 13, 2024 Matthew Hastings The central problem of physics and quantum chemistry is to find the ground state energy of some physical system governed by quantum mechanics. In mathematical terms, this means finding the lowest eigenvalue of some linear operator on a vector space... Read More video lecture Algebra of the Infrared with Twisted Masses May 10, 2024 Ahsan Z Khan The Gaiotto-Moore-Witten "Algebra of the Infrared" allows one to construct the category of supersymmetric boundary conditions for a wide class of massive N=(2,2) QFTs in two dimensions. In particular, it applies to N=(2,2) QFTs defined by a Morse... Read More video lecture Supersymmetric Approach to the Analysis of Random Band Matrices May 10, 2024 Mariya Shcherbina We discuss an application of the SUSY approach to the analysis of spectral characteristics of hermitian and non hermitian random band matrices. In 1D case the obtained integral representations for correlation functions of characteristic polynomials... Read More video lecture Invariant Sets and Hyperbolic Periodic Orbits May 10, 2024 Viktor Ginzburg The presence of hyperbolic periodic orbits or invariant sets often has an affect on the global behavior of a dynamical system. In this talk we discuss two theorems along the lines of this phenomenon, extending some properties of Hamiltonian... Read More video lecture Derived Hecke Action For Weight One Modular Forms Via Classicality May 09, 2024 Gyujin Oh It is known that a p-adic family of modular forms does not necessarily specialize into a classical modular form at weight one, unlike the modular forms of weight 2 or higher. We will explain how this obstruction to classicality leads to a "derived"... Read More video lecture The Geometric Langlands Conjecture May 06, 2024 Sam Raskin I will describe the main ideas that go into the proof of the (unramified, global) geometric Langlands conjecture. All of this work is joint with Gaitsgory and some parts are joint with Arinkin, Beraldo, Chen, Faergeman, Lin, and Rozenblyum. I will... Read More video lecture Symplectic Aspects of the Hilbert-Smith Conjecture and p-adic Actions May 06, 2024 Egor Shelukhin I will discuss a recent proof of new cases of the Hilbert-Smith conjecture for actions by homeomorphisms of symplectic nature. In particular, it rules out faithful actions of the additive p-adic group in this setting and provides further... Read More video lecture Rounding Large Independent Sets on Expanders May 06, 2024 Tim Hsieh In this talk, we will present a new approach for approximating large independent sets when the input graph is a one-sided expander—that is, the uniform random walk matrix of the graph has second eigenvalue bounded away from 1. Specifically, we show... Read More video lecture Symplectic Structures from Almost Symplectic Structures May 03, 2024 Agustin Moreno In this talk, we will consider a stabilized version of the fundamental existence problem of symplectic structures (cf. Open Problem 1 in McDuff & Salamon). Given a formal symplectic manifold, i.e. a closed manifold M with a non-degenerate 2-form and...
