If/: X->Y is a map of a space X into a space Y, we say that/ is a /oca/ connection in dimension n, provided that for every point yE.Y and every neighborhood N of y there is a neighborhood FCA7' of y such that for 0 g & ^ «-1 any map g : Sk->/-1 F extends to a map g': Bk+1-^f~1N and for any map g: 5"-¡-/"^F the map fg: 5n->F extends to a map fe: Bn+1->N. Using star-refinements of open covers and a standard approximation technique we establish the following theorem (a slightly weaker form of which has been announced by Price [2]).
ABSTRACT. A theorem is proved which generalizes both the Vietoris-Begle theorem and the cell-like theorem for spaces of finite defomation dimension. The proof is geometric and uses a double mapping cylinder trick.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
