Unitriangular basic sets, Brauer characters and coprime actions

Zhicheng Feng, Britta Späth

We show that the decomposition matrix of a given group $G$ is unitriangular, whenever $G$ has a normal subgroup $N$ such that the decomposition matrix of $N$ 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 $Irr (G)$ as an $Aut (G)$ -set for $G$ a finite quasi-simple group. Focusing on the last open case of groups of…
