Noninner Automorphisms of Order p for Finite p-Groups of Coclass 2
A. Abdollahi, S. M. Ghoraishi, Y. Guerboussa +2
Every finite -group of coclass 2 has a noninner automorphism of order leaving the center elementwise fixed.

A note on noninner automorphisms of order for finite -groups of coclass 2
A. Abdollahi, S. M. Ghoraishi, B. Wilkens
In this note, the existence of noninner automorphisms of order 2 for finite 2-groups of coclass 2 is proved. Combining our result with a recent one due to Y. Guerboussa and M. Regu…

Finite 2-groups of Class 2 with Specific Automorphism Group
A. Abdollahi, M. Ahmadi, S. M. Ghoraishi
In this paper we classify all finite 2-groups of class 2 for which every automorphism of order 2 leaving the Frattini subgroup elementwise fixed is inner. We prove that every such…
