On the inductive Alperin-McKay condition for simple groups of type A

Marc Cabanes, Britta Spaeth

As a sequel to [CS13b], we verify the so-called inductive AM-condition introduced in [Sp12] for simple groups of type A and blocks with maximal defect. This is part of the program…

Clifford theory of characters in induced blocks

Shigeo Koshitani, Britta Spaeth

We present a new criterion to predict if a character of a finite group extends. Let $G$ be a finite group and $p$ a prime. For $N ⊲ G$ , we consider $p$ -blocks $b$ and $b^{'}$ of $N$ …

Regular Sylow $d$ -Tori of classical groups and the McKay conjecture

Britta Spaeth

We prove for finite reductive groups $G$ of classical type, that every irreducible character of $L$ extends to its inertia group in $N$ , where $L$ is an abelian centraliser of a Sy…
