Mathematics Colloquium

Tuesday, April 16, 2019
4:00pm to 5:00pm
Add to Cal
Linde Hall 310
Shimura varieties, Galois representations, and torsion classes
Ana Caraiani, Department of Mathematics, Imperial College,

In this talk, I will describe joint work in preparation with Peter Scholze on torsion in the cohomology of certain unitary Shimura varieties. I will explain how the theory of perfectoid spaces and p-adic Hodge theory give new insights into the geometry and cohomology of Shimura varieties. I will also mention applications of these results to elliptic curves over imaginary quadratic fields, joint with Allen, Calegari, Gee, Helm, Le Hung, Newton, Scholze, Taylor, and Thorne.
