On p-parts of character degrees

Guohua Qian, Yong Yang

In this paper, we get the sharp bound for $∣ G / O_{p} (G) ∣_{p}$ under the assumption that either $p^{2} ∤ χ (1)$ for all $χ \in Irr (G)$ or $p^{2} ∤ ϕ (1)$ for all $ϕ\in {\rm IBr}_p…

Blocks of defect of p-solvable groups

Yong Yang

Let $p$ be a prime such that $p \geq 5$ . Let $G$ be a finite $p$ -solvable group and let $p^{a}$ be the largest power of $p$ dividing $χ (1)$ for an irreducible character $χ$ of $G$ , w…

Permutation Groups and Orbits on Power Sets

Yong Yang

Let $G$ be a permutation group of degree $n$ and let $s (G)$ denote the number of set-orbits of $G$ . We determine $in f (\frac{l o g _{2} s ( G )}{n})$ over all groups $G$ that satisfy cert…
