Non-amenable finitely presented torsion-by-cyclic groups
We construct a finitely presented non-amenable group without free non-cyclic subgroups thus providing a finitely presented counterexample to von Neumann’s problem. Our group is an extension of a group of finite exponent n >> 1 by a cyclic group, so it satisfies the identity [x, y] = 1.

We construct a finitely presented non-amenable group without free non-cyclic subgroups thus providing a finitely presented counterexample to von Neumann’s problem. Our group is an extension of a group of finite exponent n 1 by a cyclic group, so it satisfies the identity [x, y]n = 1. 1. Short history of the problem Hausdorff [14] proved in 1914 that one can subdivide the 2-sphere minus a counta...
متن کاملThe Computational Complexity of Torsion-freeness of Finitely Presented Groups
We determine the complexity of torsion-freeness of nitely presented groups in Kleene's arithmetical hierarchy as 0 2 -complete. This implies in particular that there is no e ective listing of all torsion-free nitely presented groups, or of all non-torsion-free nitely presented groups. 0. Introduction. One way of describing a group G is to give its presentation, i.e., to write G as G = hx i (i 2...
متن کاملAnalysing Finitely Presented Groups by Constructing Representations
One idea how to prove that a finitely presented group G is infinite is to construct suitable homomorphisms into infinite matrix groups. In [HoP 92] this is done by starting with a finite image H of G and solving linear equations to check whether the epimorphism onto H can be lifted to a representation whose image is an extension of a ZZ-lattice by H, thus exhibiting an infinite abelian section ...
متن کاملFinitely Presented Extensions by Free Groups
We prove here that a finitely presented group with a free quotient of rank n is an HNN-extension with n stable letters of a finitely generated group where the associated subgroups are finitely generated. This theorem has a number of consequences. In particular, in the event that the free quotient is cyclic it reduces to an elementary and quick proof of a theorem of Bieri and Strebel. 1. Finitel...
