Blocks with only one irreducible Brauer character orbit
Fuming Jiang, Kun Zhang, Yuanyang Zhou
In this paper, we confirm the Kessar-Linckelmann conjecture for blocks with abelian defect groups. More generally, we prove that if a covered block with abelian defect groups has i…

Finite groups with exactly two nonlinear irreducible -Brauer characters
Fuming Jiang, Yu Zeng
Let be a prime. We classify the finite groups having exactly two irreducible -Brauer characters of degree larger than one. The case, where the finite groups have orders not…
