Orbits of finite solvable groups on characters

Thomas Michael Keller, Yong Yang

We prove that if a solvable group A acts coprimely on a solvable group G, then A has a "large" orbit in its corresponding action on the set of ordinary complex irreducible characte…

Blocks of small defect

Yong Yang

Let $G$ be a finite solvable group, let $p$ be a prime such that $p \geq 5$ and $O_{p} (G) = 1$ , and we denote $∣ G ∣_{p} = p^{n}$ , then $G$ contains a block of defect less than or equal to $\l…
