Finite groups with a unique real $2$ -block

Yu Zeng, Fuming Jiang

Let $p$ be a prime, and let $B$ be a $p$ -block of a finite group $G$ . A $p$ -block $B$ is called \emph{real} if the set of irreducible ordinary characters contained in $B$ is invari…

Blocks with a single automorphism orbit of irreducible Brauer characters

Fuming Jiang, Kun Zhang, Yuanyang Zhou

Fix a prime $p$ . Let $G ⊴ G ~$ be finite groups such that $∣ G ~ : G ∣$ is a power of $p$ , and let $b ~$ be a block of $G ~$ with abelian defect groups…

Finite groups with exactly two nonlinear irreducible $p$ -Brauer characters

Fuming Jiang, Yu Zeng

Let $p$ be a prime. We classify the finite groups having exactly two irreducible $p$ -Brauer characters of degree larger than one. The case, where the finite groups have orders not…
