Abstract :
ABSTRACT. Let W be a non-empty subset of a free group. The automorphism a of a group G is said to be a marginal automorphism (with respect to W), if for all z € G, z la(c) € W (G), where W*(G) is the marginal subgroup of G.
In this paper, we study the concept of marginal automorphisms of a given group and we obtain a necessary and sufficient condition for a purely non-abelian finite p-group G, such that the set of all marginal automorphisms of G forms an elementary abelian p-group.
