On automorphism groups of Toeplitz subshifts [PDF]
Discrete Analysis, 2017 On automorphism groups of Toeplitz subshifts, Discrete Analysis 2017:11, 19 pp. A discrete dynamical system is a space $X$ with some kind of structure, together with a map $\sigma\colon X\to X$ that preserves the structure.

Amenable groups without finitely presented amenable covers [PDF]
Bulletin of Mathematical Sciences, 2013 The goal of this article is to study results and examples concerning finitely presented covers of finitely generated amenable groups. We collect examples of groups $G$ with the following properties: (i) $G$ is finitely generated, (ii) $G$ is amenable, e ...

The automorphism group of a finitely generated virtually abelian group
Groups Complexity Cryptology, 2016 AbstractWe describe a practical algorithm to compute the automorphism group of a finitely generated virtually abelian group. As application, we describe the automorphism groups of some small-dimensional crystallographic groups.

Fitting quotients of finitely presented abelian-by-nilpotent groups [PDF]
, 2013 We show that every finitely generated nilpotent group of class 2 occurs as the quotient of a finitely presented abelian-by-nilpotent group by its largest nilpotent normal subgroup.Comment: This second version takes into account the suggestions by the ...

Multiple holomorphs of finitely generated abelian groups [PDF]
Transactions of the American Mathematical Society, 1951 The object of this paper is to determine all cases in which two or more finitely generated abelian groups have the same holomorph(l). Let G and G' be finitely generated abelian groups and let H be the holomorph of G. Then it will be shown that H is the holomorph of G' if and only if G' is an invariant maximal-abelian subgroup of H isomorphic to G.

Finitely generated soluble groups and their subgroups [PDF]
, 2011 We prove that every finitely generated soluble group which is not virtually abelian has a subgroup of one of a small number of types.Comment: 16 ...

Abelian subgroup separability of some one-relator groups
International Journal of Mathematics and Mathematical Sciences, 2005 We prove that any group in the class of one-relator groups given by the presentation 〈a,b;[am,bn]=1〉, where m and n are integers greater than 1, is cyclic subgroup separable (or πc).

Finitely generated subgroups as von Neumann radicals of an Abelian group [PDF]
Математичні Студії, 2012 Let G be an infinite Abelian group. We give a complete characterization of those finitely generated subgroups of G which are the von Neumann radicals for some Hausdorff group topologies on G.
