ABSTRACT. In this paper we continue the study of homeomorphisms and prove an analogue of the homeomorphism extension theorem for bundles modeled on Hilbert cube manifolds; thus we generalize previous results for Ç-manifolds Hypothesis. Throughout the following let M denote a connected Q-manifold and, for matter of convenience, assume that all spaces considered are metrizable.Our notation and definitions follow that of [7] and [8].2. Separation of sets. We recall that for a bundle E = (E, p, B) and for a pair (F, U) denoting an open set of E and an open cover of F, a (F, ll)-z'soropy ifil on E is a map p = {¡lA: E x I -* E such that pQ -id, each pt is an isomorphism with support in F, and i^.lyl is limited by ll. A closed set K in the product space X x Y is an X-projective Z-set provided the projection of K into X is contained in a closed Z-set of X. A closed subset K of E is a fibre Zset provided K O p~lib) is a Z-set in p~lib) for each b e B. The purpose of this section is to prove the following theorem.
