We prove that for any finitely generated relatively hyperbolic group G and any symmetric endomorphism f of G with relatively quasiconvex image, Fixf is relatively quasiconvex subgroup of G.

We show that every virtually torsion-free subgroup of the outer automorphism group of a conjugacy separable relatively hyperbolic group is residually finite. As a direct consequence, we obtain that the outer automorphism group of a limit group is res

We show that every virtually torsion-free subgroup of the outer automorphism group of a conjugacy separable hyperbolic group is residually finite. As a result, we are able to prove that the group of outer automorphisms of every finitely generated Fuc

Bestvina, Feighn and Handel proved that every subgroup of the outer automorphism group, (Formula presented.) of the free group of rank n is either virtually finitely generated abelian or contains a nonabelian free group. In this note we consider the

Let G be a group acting on a tree T with finite edge stabilizers of bounded order. We provide, in some very interesting cases, upper bounds for the complexity of the intersection H a K of two tame subgroups H and K of G in terms of the complexities o

We discuss in the context of finite extensions two classical theorems of Takahasi and Howson on subgroups of free groups. We provide bounds for the rank of the intersection of subgroups within classes of groups such as virtually free groups, virtuall

It is shown, for a given graph group G, that the fixed point subgroup Fix φ is finitely generated for every endomorphism φ of G if and only if G is a free product of free abelian groups. The same conditions hold for the subgroup of periodic points.
