Abstract

In this paper two results concerning the construction of approximate fibrations are established. The first shows that there are approximate fibrations p : M S 2 p:M \to S^2 which are homotopic to bundle maps but which cannot be approximated by bundle maps. Here M M can be a compact Q Q -manifold or some topological n n -manifold, n 5 n \geqslant 5 . The second shows how to construct approximate fibrations p : M B p:M \to B whose fibers do not have finite homotopy type, for any B B of Euler characteristic zero. Here M M can be a compact Q Q -manifold and B B only has to be an ANR, or M M can be an n n -manifold, n 6 n \geqslant 6 , and B B must then also be a topological manifold.
