Class-preserving automorphisms of some finite $p$ -groups

Mahak Sharma, Deepak Gumber

Let $G$ be a finite $p$ -group of order $p^{5}$ , where $p$ is a prime. We give necessary and sufficient conditions on $G$ such that $G$ has a non-inner class-preserving automorphism.…

Equality of certain automorphism groups of finite $p$ -groups

Deepak Gumber, Hemant Kalra

Let $G$ be a finite $p$ -group and let Aut $(G)$ denote the full automorphism group of $G$ . In the recent past, there has been interest in finding necessary and sufficient conditions…

The conjugacy class number k(G) - a different perspective

Deepak Gumber, Hemant Kalra

Let $G$ be a finite group. Let $k (G)$ denote the number of conjugacy classes of $G$ and let $m (G)$ denote the least positive integer $n$ such that the union of any $n$ distinct non…
