The Diaconis-Graham Inequalities and Links from Permutations
Amanda Schwartz
In 1977, Diaconis and Graham proved inequalities involving different permutation statistics that measure disarray of permutations. This talk...

Colloquium: Total positivity: combinatorics, geometry, and representation theory
Xuhua He, University of Hong Kong
An invertible matrix is called totally positive if all of its minors are positive. Over the past several decades, this classical notion has...
Finite Generation of MCG(S_{g,n})

The Riemann mapping theorem is a fundamental result of one-variable complex analysis. But is it true in higher dimensions? In this talk,...
RTG Topology Geometry Dynamics. ERGODIC METHODS IN COMBINATORICS AND NUMBER THEORY
Florian Richter (EPFL)
This talk provides an introduction to the use of ergodic theory in combinatorics and number theory. We discuss how questions about...
Stochastic Kernel Topologies and Implications for Approximations, Robustness, and Learning
Serdar Yuksel, Queens University
Stochastic kernels represent system models, control policies, and measurement channels, and thus offer a general mathematical framework. We...
