If you have a question about this talk, please contact David Craven. Conference: Representations of Symmetric Groups, Hecke Algebras and KLR Algebras It is a long standing question due to Brauer to find out what the complex group algebra G, i.e., what can be deduced on the structure of G from the multiset of degrees of its irreducible characters. Concluding the work by Nguyen and Tong-Viet on quasisimple
groups, in joint work with them and Olsson, the double covers of the symmetric and alternating groups were considered. For nonabelian simple groups G, Huppert conjectured that just the character degree set (without multiplicities) determines G up to an abelian factor. For alternating groups A, this was shown by Huppert up to _{n}n=11, and by Nguyen, Tong-Viet and Wakefield for n=12,13. I will report on progress on this obtained in recent joint work with Tong-Viet and Jiping Zhang.This talk is part of the Birmingham and Warwick Algebra Seminar series. ## This talk is included in these lists:Note that ex-directory lists are not shown. |
