Hyperfocal subalgebras of hyperfocal abelian Frobenius blocks

Xueqin Hu, Kun Zhang, Yuanyang Zhou

In this paper, we introduce a class of blocks which is called hyperfocal abelian Frobenius blocks.This class of blocks is an analogous version of the block with abelian defect grou…

Blocks with abelian defect groups of rank 2 and one simple module

Xueqin Hu

In this paper, we investigate the block that has an abelian defect group of rank $2$ and its Brauer correspondent has only one simple module. We will get an isotypy between the blo…

Blocks with the hyperfocal subgroup $Z_{2^{n}} \times Z_{2^{n}}$

Xueqin Hu, Yuanyang Zhou

In this paper, we calculate the numbers of irreducible ordinary characters and irreducible Brauer characters in a block of a finite group $G$ , whose associated fusion system over a…
