Titre Arithmetic and representation theory of wild character varieties
Horaire10:30 à 11:30
RésumeI will start with an overview of the arithmetic harmonic analysis technique to obtain information on the mixed Hodge polynomial of tame character varieties. In the second part I will discuss some wild character varieties, and how the representation theory of Yokonuma-Hecke algebras can be used to get results on the mixed Hodge polynomial of character varieties. This is joint work with Martin Mereb, Michael Wong and Dimitri Wyss.
