Extensions of characters in type D and the inductive McKay condition, II
Britta Späth
We determine the action of the automorphism group Aut on the set of irreducible characters Irr for all finite quasi-simple groups . For groups of Lie type, this includ…
Unitriangular basic sets, Brauer characters and coprime actions
Zhicheng Feng, Britta Späth
We show that the decomposition matrix of a given group is unitriangular, whenever has a normal subgroup such that the decomposition matrix of is unitriangular, $G/N…
Extensions of characters in type D and the inductive McKay condition, I
Britta Späth
This is a contribution to the study of as an -set for a finite quasi-simple group. Focusing on the last open case of groups of…
Inductive McKay condition for finite simple groups of type C
Marc Cabanes, Britta Späth
We verify the inductive McKay condition for simple groups of Lie type C, namely finite projective symplectic groups. This contributes to the program of a complete proof of the McKa…
On Blocks with One Modular Character
Gunter Malle, Gabriel Navarro, Britta Späth
Suppose that is a Brauer -block of a finite group with a unique modular character . We prove that is liftable to an ordinary character of (which moreover is $…
Invariant blocks under coprime actions
Gunter Malle, Gabriel Navarro, Britta Späth
If a finite group acts coprimely as automorphisms on a finite group , then the -invariant Brauer -blocks of are exactly those that contain -invariant irreducibl…
Equivariant character correspondences and inductive McKay condition for type A
Marc Cabanes, Britta Spaeth
As a step to establish the McKay conjecture on character degrees of finite groups, we verify the inductive McKay condition introduced by Isaacs-Malle-Navarro for simple groups of L…
