SUMMARY:Séminaire TNGA : Samuel Frengley
DESCRIPTION:Orateur : Samuel Frengley (INRIA et LIX) \n\n\n\nTitre : Galois groups of abelian varieties and exceptional Tate classes \n\n\n\nRésumé : The Tate conjecture states the codimension r cycles on a variety can be described in terms the étale cohomology H^{2r}. I will discuss when the Tate conjecture for abelian varieties over finite fields can be proved by intersecting divisors\, extending previous results of Dupuy–Kedlaya–Zureick-Brown\, Lenstra–Zarhin\, Tankeev\, and Zarhin. This is joint work with Santiago Arango-Piñeros and Sameera Vemulapalli.
