AUTOMORPHISM GROUP OF GROUPS OF ORDER pqr

H"{o}lder in 1893 characterized all groups of order $pqr$ where  $p>q>r$ are prime numbers. In this paper,  by using new presentations of these groups, we compute their full automorphism group.

Splitting the Automorphism Group of an Abelian P-group

Let G be an abelian p-group sum of finite homocyclic groups Gi. Here, we determine in which cases the automorphism group of G splits over kerσ, where σ :Aut(G) → ∏ iAut(Gi/pGi) is the natural epimorphism. 1. Preliminaries Throghout this paper, p is an arbitrary prime and r is a fixed ordinal number. Let G = ⊕i≤rGi be an abelian p-group, such that Gi is an homocyclic group of exponent pi and fin...

THE AUTOMORPHISM GROUP OF FINITE GRAPHS

Let G = (V,E) be a simple graph with exactly n vertices and m edges. The aim of this paper is a new method for investigating nontriviality of the automorphism group of graphs. To do this, we prove that if |E| >=[(n - 1)2/2] then |Aut(G)|>1 and |Aut(G)| is even number.

THE AUTOMORPHISM GROUP OF A FINITE MINIMAL NON-ABELIAN p-GROUP

Determining the order and the structure of the automorphism group of a finite p-group is an important problem in group theory. There have been a number of studies of the automorphism group of p-groups. Most of them deal with the order of Aut(G), the automorphism group of G, see for example [1] and [6]. Moreover various attempts have been made to find a structure for the automorphism group of a ...

On the fixing number of graphs with abelian automorphism group

The fixing number of a graph G is the cardinality of a smallest set of vertices of G that is not fixed by any non-trivial automorphism of G. In this paper we investigate the fixing number of finite graphs with abelian automorphism group.

THE AUTOMORPHISM GROUP OF FINITE ABELIAN p-GROUPS

The endomorphisms and the automorphisms of a finite abelian p-group are presented in an efficient way. The order of the automorphism group is computed and its structure investigated. Finally the characteristic subgroups are described for p > 2 and the fully invariant subgroups for any p.
