|Title:||The Sigma(2)-conjecture for metabelian groups: the general case|
|Abstract:||The Bieri-Neumann-Strebel invariant Sigma(m) (G) of a group G is a certain subset of a sphere that contains information about finiteness properties of subgroups of G. In case of a metabelian group G the set Sigma(1) (G) completely characterizes finite presentability and it is conjectured that it also contains complete information about the higher finiteness properties (FPm-conjecture). The Sigma(m)-conjecture states how the higher invariants are obtained from Sigma(1) (G). In this paper we prove the Sigma(2)-conjecture. (C) 2004 Elsevier Inc. All rights reserved.|
