 Abstract
Let N be a Closed n-manifold with residually finite, torsion free (N) and finite H,(N). Suppose that k/(N)=0 for 1 < k < n-1. We show that N is a codimension-n PL fibrator if and only if N does not cover itself regularly and cyclically up to homotopy type, provided (N) satisfies a certain condition.
