Abstract

A non-trivial separable metric space XX is called an almost homology nn-manifold if the homology groups Hk(X,X\{x},Z)H_k(X,X\backslash\{x\},\mathbb Z) are trivial for all xXx\in X and all k=0,1,..,n1k=0,1,..,n-1. We provide a necessary and sufficient condition locally compact homogeneous ANRANR-spaces or strongly locally homogeneous ANRANR-spaces to be almost homology nn-manifolds.
