NUMBER THEORY
April 7, 2021 3:00 pmThe geometric Satake equivalence due to Lusztig, Drinfeld, Ginzburg, Mirković and Vilonen is an indispensable tool in the Langlands program. Versions of this equivalence are known for different cohomology theories such as...

RANDOM MATRIX
April 7, 2021 2:00 pmIn many problems in statistical learning, random matrix theory, and statistical physics, one needs to simulate dynamics on random matrix ensembles. A classical example is to use iterative methods to...

DIFFERENTIAL GEOMETRY
April 6, 2021 8:00 amThis talk will be about refined curve counting on local P^2, the noncompact Calabi-Yau 3-fold total space of the canonical line bundle of the projective plane. I will explain how...

MATHEMATICAL PICTURE LANGUAGE
April 6, 2021 10:00 amThe space spanned by homotopy classes of free oriented loops on a 2-manifold carries an interesting algebraic structure (a Lie bialgebra structure) due to Goldman and Turaev. This structure is...
