title: Fiber-homotopy equivalence
text: In algebraic topology, a fiber-homotopy equivalence is a map over a space B that has homotopy inverse over B It is a relative analog of a homotopy equivalence between spaces. Given maps p: D → B, q: E → B, if ƒ: D → E is a fiber-homotopy equivalence, then for any b in B the restriction - f : p − 1 → q − 1 is a homotopy equivalence. If p, q are fibrations, this is always the case for homotopy equivalences by the next proposition.
