A new class of homology and cohomology 3-manifolds

Abstract

We show that for any set of primes P there exists a space MP which is a homology and cohomology 3-manifold with coefficients in Zp for p∈ P and is not a homology or cohomology 3-manifold with coefficients in Zq for q∈ P. Moreover, MP is neither a homology nor cohomology 3-manifold with coefficients in Z or Q.
