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…
On semisimple classes and component groups in type
Marc Cabanes, Britta Späth
In adjoint reductive groups of type we show that for every semisimple element , its centralizer splits over its connected component, i.e., $C_H(s) = C_H(s)^\cir…
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…
