|Title:||More about the geometric invariants Sigma(m)(G) and Sigma(m)(G, Z) for groups with normal locally polycyclic-by-finite subgroups|
|Abstract:||The main result of the paper is that the real characters of a group G of type FPm (F-m respectively) that do not vanish on a normal locally polycyclic-by-finite sub-group represent elements of the geometric invariant Sigma (m)(G, Z) (Sigma (m)(G) respectively). In the case m = 2 a stronger result is proved. Some consequences of the main result. are considered.|
