An Endomorphism of a Finitely Generated Residually Finite Group
نویسنده
چکیده
Let φ : G→ G be an endomorphism of a finitely generated residually finite group. R. Hirshon asked if there exists n such that the restriction of φ to φn(G) is injective. We give an example to show that this is not always the case.

The Quasi-morphic Property of Group
A group is called morphic if for each normal endomorphism α in end(G),there exists β such that ker(α)= Gβ and Gα= ker(β). In this paper, we consider the case that there exist normal endomorphisms β and γ such that ker(α)= Gβ and Gα = ker(γ). We call G quasi-morphic, if this happens for any normal endomorphism α in end(G). We get the following results: G is quasi-morphic if and only if, for any ...
متن کاملFixed Subgroups of Endomorphisms of Free Products
Let G = ∗ i=1 Gi and let φ be a symmetric endomorphism of G. If φ is a monomorphism or if G is a finitely generated residually finite group, then the fixed subgroup Fix(φ) = {g ∈ G : φ(g) = g} of φ has Kurosh rank at most n.
متن کاملFinitely generated groups with polynomial index growth
We prove that a finitely generated soluble residually finite group has polynomial index growth if and only if it is a minimax group. We also show that if a finitely generated group with PIG is residually finite-soluble then it is a linear group. These results apply in particular to boundedly generated groups; they imply that every infinite BG residually finite group has an infinite linear quoti...
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 کاملPolynomial Maps over p-Adics and Residual Properties of Mapping Tori of Group Endomorphisms
This paper is a continuation of paper [1] where we proved that for every linear finitely generated group G and any injective endomorphism φ of G, the mapping torus of φ is residually finite. The mapping torus of φ is the following ascending HNN extension of G: HNNφ (G) = 〈G, t | txt−1 = φ(x)〉 where x runs over a (finite) generating set of G. Probably, the most important mapping tori are mapping...
