Direct factors of profinite completions and decidability
Martin R. Bridson
We consider finitely presented,residually finite groups and finitely generated normal subgroups such that the inclusion induces an isomorphism from the…
Decision problems and profinite completions of groups
Martin R. Bridson
We consider pairs of finitely presented, residually finite groups $P\hookrightarrow\G$ for which the induced map of profinite completions $\hat P\to \hat\G$ is an isomorphism. We p…
Finitely presented residually free groups
Martin R. Bridson, James Howie, Charles F. Miller +1
We establish a general criterion for the finite presentability of subdirect products of groups and use this to characterize finitely presented residually free groups. We prove that…
The quadratic isoperimetric inequality for mapping tori of free group automorphisms
Martin R. Bridson, Daniel Groves
If F is a finitely generated free group and ϕis an automorphism of F then F \rtimes_ϕZ satisfties a quadratic isoperimetric inequality.
