Arka Adhikari (Stanford)

 

Abstract: In this talk, I will give an overview of statistical physics and give an introduction to spin glasses.

Unlike many classical models , like the Ising model, which has structurally regular properties, spin glasses

are pattern-less with an irregular distribution.…

András Vasy (Stanford)

I will talk about the analytic aspects of black holes, especially waves and stability questions, particularly in the context of Kerr-de Sitter spaces (positive cosmological constant).

Yakov Eliashberg (Stanford)

Abstract: I will explain how the  count of algebraic curves in the complex projective plane can be reduced to a solution of a Hamilton-Jacobi equation.

Jonathan Winghong Luk (Stanford)

Abstract: I will discuss Boltzmann's celebrated H theorem for collisional kinetic equations such as the Boltzmann equation or the Landau equation. I will explain what it does and does not imply for the nonlinear flow and describe some open problems.

Abstract: The "area" functional takes a submanifold of a Riemannian manifold and returns its area. A natural idea is to try to use Morse theory to find critical points of the area functional (of considerable interest to geometers, these are called minimal submanifolds). I will describe what we…

Mohammed Abouzaid (Stanford)

Inspired by physicist, Atiyah and Segal initiated an area of mathematics which is the sometimes called "topological field theory." While this can be a useful way of thinking about algebra using pictures, it is essentially impossible to produce genuine new examples using only topology. The…

Amir Dembo (Stanford)

In this talk, based on joint works with Nicholas Cook, Huy Tuan Pham and Sohom Bhattacharya, I will discuss recent developments in the study of the upper tails for counts of several fixed subgraphs in a large sparse random graph (such as Erdős–Rényi or uniformly d- regular). These…

Persi Diaconis (Stanford)

This is the story of understanding 'things' by asking 'what does a typical thing 'look like'. The things can be finite (permutations, elements of a finite group, graphs, or integers between 1 and N). They can also be infinite (random matrix theory asks about the eigenvalues of 'typical…

Xinwen Zhu (Stanford)
I will give a flavor of geometric representation theory by discussing one particular object: equivariant homology of affine Grassmannian (which is some infinite-dimensional algebro-geometric object). I will discuss its relation to topology (Bott periodicity), mathematical physics (Coulomb…

Andras Vasy (Stanford)
Microlocal analysis is about localizing in phase space, i.e. physically in combined position and momentum, and mathematically in the cotangent bundle of an underlying space (the position space). For instance, one can ask where a function, or distribution, is singular (by various measures) and…
