Decomposability of finitely generated torsion-free nilpotent groups

Gilbert Baumslag, Charles F Miller, Gretchen Ostheimer

Journal article  |  2016  |  INTERNATIONAL JOURNAL OF ALGEBRA AND COMPUTATION

We describe an algorithm for deciding whether or not a given finitely generated torsion-free nilpotent group is decomposable as th..

ON THE FINITE PRESENTATION OF SUBDIRECT PRODUCTS AND THE NATURE OF RESIDUALLY FREE GROUPS

Martin R Bridson, James Howie, Charles F Miller, Hamish Short

Journal article  |  2013  |  AMERICAN JOURNAL OF MATHEMATICS

We establish virtual surjection to pairs (VSP) as a general criterion for the finite presentability of subdirect products of group..

Subgroups of free metabelian groups

Gilbert Baumslag, Charles F Miller, Gretchen Ostheimer

Journal article  |  2010  |  GROUPS GEOMETRY AND DYNAMICS

In 1954 A. G. Howson proved that the intersection of two finitely generated subgroups of a free group is again finitely generated...

Subgroups of direct products of limit groups

Martin R Bridson, James Howie, Charles F Miller, Hamish Short

Journal article  |  2009  |  ANNALS OF MATHEMATICS

If Γ1,...,Γn are limit groups and S ⊂ Γ1 ×...×Γn is of type FPn(Q{double-struck}) then S contains a subgroup of finite index that ..

Reflections on some groups of B. H. Neumann

Gilbert Baumslag, Charles F Miller

Journal article  |  2009  |  JOURNAL OF GROUP THEORY

In 1937, B. H. Neumann constructed a family of continuously many, non-isomorphic two-generator groups. We will prove that none of ..

Structure and finiteness properties of subdirect products of groups

Martin R Bridson, Charles F Miller

Journal article  |  2009  |  PROCEEDINGS OF THE LONDON MATHEMATICAL SOCIETY

We investigate the structure of subdirect products of groups, particularly their finiteness properties. We pay special attention t..
