Unitary representations of fundamental groups of 3-manifolds




Abstract: We consider for 3-manifolds with boundary the general problem of extending representations, or equivalently flat bundles, from (part of) the boundary to the whole 3-manifold. The solutions are expressed in terms of surprisingly simple rational homology criteria.
