Title: Character sheaves and their restriction to mixed conjugacy classes.
Abstract: Introduced by Lusztig in the eighties, character sheaves are the geometrical counterpart of irreducible representations of finite groups of Lie type. Defined over algebraic groups, they allow us to use geometrical tools to deduce information on the characters of the associated finite groups. In this talk, I'll recall the definition of character sheaves before explaining how to compute their restriction to conjugacy classes (to some extent). This work was part of my PhD thesis under the supervision of Olivier Dudas and Gunter Malle.
