A reduction theorem for the blockwise Navarro Alperin weight conjecture via H-triples

Zhicheng Feng, Qulei Fu, Yuanyang Zhou

The Galois Alperin weight (GAW) conjecture has been reduced to the inductive GAW condition for simple groups. We proceed in two steps to refine this reduction. First, we propose th…

Generic weights for finite reductive groups

Zhicheng Feng, Gunter Malle, Jiping Zhang

This paper is motivated by the study of Alperin's weight conjecture in the representation theory of finite groups. We generalize the notion of $e$ -cuspidality in the $e$ -Harish-Cha…

Alperin's bound and normal Sylow subgroups

Zhicheng Feng, J. Miquel Martínez, Damiano Rossi

Let $G$ be a finite group, $p$ a prime number and $P$ a Sylow $p$ -subgroup of $G$ . Recently, G. Malle, G. Navarro, and P. H. Tiep conjectured that the number of $p$ -Brauer characte…

Character triples and weights

Zhicheng Feng

We define a new relation between character triples and prove some Clifford theory properties for weights in terms of character triples.
