Cohomological Characterization of Hyperbolic Groups
The nitely presented group G is hyperbolic ii H 2 (1) (G; ` 1) = 0. I have established the following result, full details for which will appear in a forthcoming paper. Theorem 1. The nitely presented group G is hyperbolic ii H 2 (1) (G; ` 1) = 0. For the deenition of thè 1-cohomology, see Ge1]. The coeecient group`1 here is the Banach space of bounded functions on a countably innnite set in the...
متن کاملAmalgamated Products and Properly 3-realizable Groups
In this paper, we show that the class of all properly 3-realizable groups is closed under amalgamated free products (and HNN-extensions) over finite groups. We recall that G is said to be properly 3-realizable if there exists a compact 2-polyhedron K with π1(K) = G and whose universal cover K̃ has the proper homotopy type of a 3-manifold (with boundary).

A finitely presented group G is word hyperbolic iff H2 (∞) (G, l∞) = 0. §
متن کاملOn bounded cohomology of amalgamated products of groups
We investigate the structure of the singular part of the second bounded cohomology group of amalgamated products of groups by constructing an analog of the initial segment of the Mayer-Vietoris exact cohomology sequence for the spaces of pseudocharacters.
متن کاملKnapsack in Graph Groups, HNN-Extensions and Amalgamated Products
It is shown that the knapsack problem, which was introduced by Myasnikov et al. for arbitrary finitely generated groups, can be solved in NP for graph groups. This result even holds if the group elements are represented in a compressed form by SLPs, which generalizes the classical NP-completeness result of the integer knapsack problem. We also prove general transfer results: NP-membership of th...
