NT seminar today: Sameera Vemulapalli

[Bianca Viray]

Hello everyone,

Today in the number theory seminar we are happy to have Sameera Vemulapalli from Harvard University, who will speak on "Some cases of the Tate conjecture for abelian varieties over finite fields" (abstract below). As usual we will go to lunch with the speaker after the talk.

Abstract: In 1963, Tate conjectured that the algebraic cycles of a variety can be described in terms of the Galois invariants of certain étale cohomology groups. In this talk, I'll discuss a proof of several new cases of the Tate conjecture for abelian varieties over finite fields, extending previous results of Dupuy--Kedlaya--Zureick-Brown, Lenstra--Zarhin, Tankeev, and Zarhin. This is joint work with Santiago Arango-Piñeros and Sam Frengley.
