Cours de M2 à Paris-Diderot (2014) : Théorèmes de réductions aux quasi-simples pour les représentations des groupes finis


My research area

My primary interest was in finite groups. A group is a fascinating object, being very constraint, almost impossible, yet some simple groups have just a finite number of elements. As anyone knows, finite groups are either solvable or contain in a distinguished way subgroups that are finite versions of Lie groups.

This is my reason for having worked mainly on finite groups of Lie type and their representations. More precisely : modular representations or modular aspects of ordinary representations of finite reductive groups. Enguehard and I tried to give an introduction to the whole subject in our book : "Representation theory of finite reductive groups", Cambridge, 2004.

Recent work by several authors has shown that most well-known conjectures on representations of finite groups can be deduced from so-called "inductive" statements on quasi-simple groups. This is due to Isaacs-Malle-Navarro (2007) for McKay's conjecture on character degrees, Navarro-Tiep (2011) for Alperin's weight conjecture, Späth (2012) for their block versions, Navarro-Späth (2013) for Brauer's height zero conjecture. In joint work with Späth, I am involved in checking the inductive statements for McKay conjecture in the not known cases of groups of Lie type for non-defining primes (the current state of this checking).
