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 sparsely Abelian, hopfian fundamental group and X(N) $\neq$ 0 is a codimension-(t + 1) PL fibrator.

Keywords

approximate filbration; degree of a map; codimension-k fibrator; m-fibrator; Hopfian manifold; normally cohopfian; sparsely Abelian;
