Finite groups in which every irreducible character has either $p^{'}$ -degree or $p^{'}$ -codegree

Guohua Qian, Yu Zeng

For an irreducible complex character $I ¨ $ of a finite group $G$ , the codegree of $I ¨ $ is defined by $∣ G : ker (I ¨ ) ∣/ I ¨ (1)$ , where $ker (I ¨ )$ is the kernel of $I ¨ $ . Given a prime $p$ ,…

Character codegrees, kernels, and Fitting heights of solvable groups

Guohua Qian, Yu Zeng

For an irreducible character $I ¨ $ of a finite group $G$ , let $cod (I ¨ ) := ∣ G : ker (I ¨ ) ∣/ I ¨ (1)$ denote the codegree of $I ¨ $ , and let $cod (G)$ be the set of irreducibl…
