Covering graph

Summary

In the mathematical discipline of graph theory, a graph CC is a covering graph of another graph GG if there is a covering map from the vertex set of CC to the vertex set of GG. A covering map ff is a surjection and a local isomorphism: the neighbourhood of a vertex vv in CC is mapped bijectively onto the neighbourhood of f(v)f(v) in GG.
