A Cohomological Criterion for a Finitely Presented Group to Be Infinite
نویسنده
چکیده
The problem of proving that a given finitely presented group G is infinite can be very difficult (or impossible) in general, but there are several possible approaches that can be tried, some of which can be rendered much more effective with the assistance of computers. To this list, we add another one, which can be applied if an epimorphism of G onto a finite group H is known. The idea depends on the following criterion.

FPoo GROUPS AND HNN EXTENSIONS BY KENNETH S. BROWN AND ROSS GEOGHEGAN
A group G is said to be of type FPoo if the ZG-module Z admits a projective resolution (Pi) of finite type (i.e., with each Pi finitely generated). If G is finitely presented, this is equivalent by Wall [5, 6] to the existence of an Eilenberg-Mac Lane complex K(G, 1) of finite type (i.e., with finitely many cells in every dimension). Up to now, all known torsion-free groups of type FPoo have ha...
متن کاملFirst Cohomology, Rigidity and Deformations of Isometric Group Actions
In 1964, Weil gave a criterion for local rigidity of a homomorphism from a finitely generated group Γ to a finite dimensional Lie group G in terms of cohomology of Γ with coefficients in the Lie algebra of G. This note announces a generalization of Weil’s result to a class of homomorphisms into certain infinite dimensional Lie groups, namely diffeomorphism groups of compact manifolds. This give...

Given a topological group G, and a finitely generated group Γ, a homomorphism π : Γ→G is locally rigid if any nearby by homomorphism π is conjugate to π by a small element of G. In 1964, Weil gave a criterion for local rigidity of a homomorphism from a finitely generated group Γ to a finite dimensional Lie group G in terms of cohomology of Γ with coefficients in the Lie algebra of G. Here we ge...

متن کاملAutomorphisms of Pro-p groups of finite virtual cohomological dimension
Let G be a pro-p group of finite cohomological dimension and type FP∞ and T is a finite p-group of automorphisms of G. We prove that the group of fixed points of T in G is again a pro-p group of type FP∞ (in particular it is finitely presented). Moreover we prove that a pro-p group G of type FP∞ and finite virtual cohomological dimension has finitely many conjugacy classes of finite subgroups.
