Chapter , Problem 70E(choose chapter or problem)
Show that if a bipartite graph G = (V. E) is n-regular for some positive integer n (see the preamble to Exercise 53) and (V1, V2) is a bipartition of V, then | V1 | = |V2|. That is, show that the two sets in a bipartition of the vertex set of an n-regular graph must contain the same number of vertices.
