... function of a regular covering of G is a product of L -functions of G. Stark and Terras [16] treated zeta functions of bipartite coverings of graphs. Feng, Kwak and Kim [2] gave a decomposition formula ... cycles of a graph G corresponds to a unique conjugacy class of the fundamental group π 1 (G, v) of G at a vertex v of G. The (Ihara) zeta function of a graph G is d...
