A map such that every point of has an open neighborhood for which is a disjoint union of open sheets, each mapped homeomorphically onto by .
A covering is a map together with topologies on both and satisfying the evenly-covered-neighborhood condition; it is not structure on one topological space alone.

This is an authored directed relation from the source endpoint to the target endpoint.
For a path-connected, locally path-connected, semilocally simply connected space, connected covering spaces correspond to conjugacy classes of subgroups of the fundamental group.
Record a genuine theorem implication that is not part of the target definition; these edges may point toward a weaker structure.

Give and topologies and a continuous surjection ; require every point of to have an evenly covered open neighborhood.
Feed several structures into a construction junction and impose compatibility between them.
