Jean-Baptiste Teyssier - 15h45 - Characteristic cycle for étale sheaves and applications.

Salle Grisvard, IHP, Paris

We will explain the notions of singular support and characteristic cycle for étale sheaves constructed by Beilinson and Saito respectively. We will then give applications to the cohomology of étale sheaves, some of which obtained in collaboration with Haoyu Hu.
