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. We only need to show the existence of F ~x for some neighbourhood N x of any given point x ∈ X.
