چکیده
Bestvina, Feighn and Handel proved that every subgroup of the outer automorphism group, Out(Fn), free group rank n is either virtually finitely generated abelian or contains a nonabelian group. In this note we consider more general situation Out(G) free-by-finite G. We show translation discrete

Automorphisms of Free Groups Have Finitely Generated Fixed Point Sets
An automorphism of a finitely generated free group F extends to a homeomorphism of the end completion E of F. The set of fixed points of this homeomorphism is finitely generated in a certain sense. In particular this implies that the subgroup of elements fixed by the automorphism is finitely generated in the usual sense. The emphasis on E instead of F in this paper is analogous to Thurston’s st...
متن کاملOuter Automorphisms of Locally Finite p-Groups∗
Every group is an outer automorphism group of a locally finite p-group. This extends an earlier result [3] about countable outer automorphism groups. It is also in sharp contrast to results concerning the existence of outer automorphisms of nilpotent groups in [6, 13, 14].
متن کاملOn the Outer Automorphism Groups of Finitely Generated, Residually Finite Groups
Bumagin–Wise posed the question of whether every countable group can be realised as the outer automorphism group of a finitely generated, residually finite group. We give a partial answer to this problem for recursively presentable groups.
متن کاملOuter automorphisms of free Burnside groups
In this paper, we study some properties of the outer automorphism group of free Burnside groups of large odd exponent. In particular, we prove that it contains free and free abelian subgroups.
متن کاملParageometric Outer Automorphisms of Free Groups
We study those fully irreducible outer automorphisms φ of a finite rank free group Fr which are parageometric, meaning that the attracting fixed point of φ in the boundary of outer space is a geometric R-tree with respect to the action of Fr, but φ itself is not a geometric outer automorphism in that it is not represented by a homeomorphism of a surface. Our main result shows that the expansion...
