Covering graph

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