Abstract: 

Co-Author Stefan Friedl (Universität Regensburg)

Given a degree-one map  between two aspherical compact orientable 3-manifolds it is a natural question to find out extra conditions to ensure that it is in fact homotopic to a homeomorphism. We will give two criteria in term of virtual ranks and of virtual heegaard genera. We will also discuss the knot spaces case and some open questions.
