# {{senseid|en|top_sp}}{{lb|en|topology}} A special kind of [[map]] that establishes a relationship between two [[topological space]]s in the sense that, under the [[action]] of the map, the one looks [[local]]ly like several copies of the second: Formally, a [[continuous]] [[map]] <math> \pi : E \rightarrow X</math> between [[topological space]]s such that there exists, for every point <math>x</math> in <math>X</math>, a [[discrete]] [[space]] <math>D_x</math> and an [[open]] [[neighborhood]] <math>U</math> of <math>x</math> such that <math>\pi^{-1}(U)= \displaystyle \bigsqcup_{d \in D_x} V_d </math> and <math>\pi|_{V_d}:V_d \rightarrow U </math> is a [[homeomorphism]] for every <math>d \in D_x </math>.

=====Usage notes=====
In sense {{senseno|en|top_sp}}, properly, the map <math>\pi</math> is the covering, and <math>E</math> is called the [[covering space]], but by [[abuse of terminology]], "covering" may refer to <math>E</math>, "covering space" may refer to <math>\pi</math>, and either may refer to the [[tuple]] <math>(E, \pi)</math>.
