Title:
Some aspects of Lefschetz theorems in algebraic geometry

Speaker:
Helene Esnault

Abstract:
We shall review some Lefschetz theorems which enabled Deligne and Drinfeld to prove Deligne’s conjectures in Weil II on companions and finiteness of l-adic sheaves. We shall present some natural questions linked to their proof.
