In this paper we study $IF$-groups, i.e., groups containing proper fully invariant subgroups isomorphic to the group itself. We prove some general properties of $IF$-groups and establish the connection between separable $IF$-groups and their basic subgroups. Torsion complete $IF$-groups are described in detail.
Mots-clés : $IF$-group, torsion complete group.
Keywords: fully invariant subgroup, wide subgroup, Ulm-Kaplansky invariants
