ALGEBRAIC DYNAMICS
April 9, 2021 10:00 amCanonical heights are a standard tool of arithmetic dynamics over global fields. When studying families of dynamical systems, or systems over larger fields, however, there are significant geometric obstacles to...

OPEN NEIGHBORHOOD
April 7, 2021 4:30 pmI will talk, pretty casually, about random walks, which I first learned about as part of my Harvard undergrad thesis in finite group theory, and which turn out to be...

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...
