A note on commuting automorphisms of some finite $p$ -groups

Sandeep Singh, Deepak Gumber

An automorphism $α$ of a group $G$ is called a commuting automorphism if each element $x$ in $G$ commutes with its image $α (x)$ under $α$ . Let $A (G)$ denote the set of all commutin…

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.

Automorphisms of groups and converse of Schur's theorem

Deepak Gumber, Hemant Kalra, Sandeep Singh

An automorphism of a group G is called an IA-automorphism if it induces the identity automorphism on the abelianized group G/G'. Let IA(G) denote the group of all IA-automorphisms…

On class preserving automorphisms of groups of order 32

Deepak Gumber, Hemant Kalra

We study class preserving automorphisms of groups of order thirty two and prove that only two groups have non-inner class preserving automorphisms.
