SOME MANIFOLDS WITH NONZERO EULER CHARACTERISTIC AS PL FIBRATORS
Im, Young-Ho;

Abstract
Approximate fibrations form a useful class of maps. By definition fibrators provide instant detection of maps in this class, and PL fibrators do the same in the PL category. We show that every closed s-hopfian t-aspherical manifold N with some algebraic conditions and X(N) $\small{\neq}$ 0 is a codimension-(2t + 2) PL fibrator.
