On $p$ -parts of conjugacy class sizes and the index of the $p$ -core

Yu Zeng, Jinbao Li, Yong Yang

For a prime $p$ and an arbitrary finite group $G$ , we show that if $p^{2}$ does not divide the size of each conjugacy class of \emph{ $p$ -regular} element (element of order not divi…

On groups with square-free gcd of character degree and codegree

Karam Aldahleh, Alan Kappler, Neil Makur +1

Let $G$ be a finite group and $I ¨ $ be an irreducible character of $G$ . The codegree of $I ¨ $ is defined as $I ¨ ^{c} (1) = \frac{∣ G : k e r I ¨ ∣}{I ¨ ( 1 )}$ . In a paper by Gao, Wang, and Chen, i…
