Web4 G-sets, G-spaces and Covering Spaces Theorem 13 Assume that X is path-connected and locally path-connected. Then any π-map F 1 → F 2 extends uniquely to a map f:X˜ 1 → X˜ 2 of covering spaces over X. Proof As X˜ 1 is a covering space of X, it too is locally path-connected, and its path components are therefore open. WebA map p: E → B is called a fibration (or Hurewicz fibration) if p has HLP for any space. Theorem 3.18. A covering is a fibration. Proof. Let p: E → B,f: X → B,f ~: X → E,F: X ×I → B be the data as in Definition 3.16.
