Algebra Seminar by Meinolf Geck

All members of the department are welcome: undergraduates, postgraduates, postdocs, teaching staff, technical staff - anyone who would like to attend and learn a little bit about what our speakers do in their research career. Members from other disciplines within the School, and the wider University community, are also welcome to attend.

All PhD students in Chemistry are expected to attend as part of their PhD training.

On the Frobenius-Schur indicators of unipotent characters

Let G be a finite group of Lie type. If G is of split type, then Lusztig and Vogan have recently established a remarkable identity involving the Frobenius-Schur indicators of the unipotent characters of G and Kottwitz' involution module for the Weyl group W of G. In joint work with Malle, we have extended this to non-split groups G. The main difficulty consists of dealing with extensions of characters of W to the semidirect product of W by an automorphism of W.
