fibre map

A fibre map is a map of topological spaces $f:E\rightarrow B$ , for which there exists a space $F$ , such that any point of $B$ is contained in some neighbourhood $U$ satisfying the following: on $f^{-1}U$ , $f$ restricts to the natural projection $F\times U\rightarrow U$ , via some homeomorphic identification of $f^{-1}U$ with $F\times U$ .

One class of examples are covering maps. Another example is the map $SO_{3}\rightarrow S^{2}$ sending a rotation to the point it sends the “North Pole” to.
