Finite $p$ -groups with minimum number of central automorphisms fixing the center element-wise

Deepak Gumber, Mahak Sharma

We characterize finite $p$ -groups $G$ of order up to $p^{7}$ for which the group of central automorphisms fixing the center element-wise is of minimum possibe order.

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.…

On central automorphisms of finite p-groups

Deepak Gumber, Mahak Sharma

We characterize all finite p-groups G of order p^n(n\leq 6), where p is a prime for n\leq 5 and an odd prime for n = 6, such that the center of the inner automorphism group of G is…
