Olivier Dudas, Gunter Malle
We prove a long-standing conjecture of Geck which predicts that cuspidal unipotent characters remain irreducible after -reduction. To this end, we construct a progenerator fo…

Categorical actions on unipotent representations of finite classical groups
Olivier Dudas, Michela Varagnolo, Eric Vasserot
We review the categorical representation of a Kac-Moody algebra on unipotent representations of finite unitary groups in non-defining characteristic given by the authors. Then, we…
