Amenability-Like properties of C(X,A)

S. Ghoraishi, A. Mahmoodi, A. R. Medghalchi

Let $A$ be a Banach algebra and $X$ be a compact Hausdorff space. Given homomorphisms $σ \in H o m (A)$ and $τ \in H o m (C (X, A))$ , we introduce induced homomorphisms $\tildeσ\in Hom(C(X…

$p$ -Groups for which each outer $p$ -automorphism centralizes only $p$ elements

Alireza Abdollahi, S. Mohsen Ghoraishi

An automorphism of a group is called outer if it is not an inner automorphism. Let $G$ be a finite $p$ -group. Then for every outer $p$ -automorphism $ϕ$ of $G$ the subgroup $C_G(ϕ)=…

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…
