Title: Finiteness Conditions And Pdr-group Covers Of Pdn -complexes
Author: Hillman J.A.
Kochloukova D.H.
Abstract: We show that an infinite cyclic covering space M′ of a PD n -complex M is a PD n-1-complex if and only if χ(M) = 0, M′ is homotopy equivalent to a complex with finite [(n-1)/2]-skeleton and π1(M′) is finitely presentable. This is best possible in terms of minimal finiteness assumptions on the covering space. We give also a corresponding result for covering spaces M ν with covering group a PD r -group under a slightly stricter finiteness condition. © Springer-Verlag 2007.
