Ihara Zeta Function and Spectrum of the Cone Over a Semiregular Bipartite Graph

In this paper, a formula for the Ihara zeta function of the cone over a semiregular bipartite graph is derived. Using this formula, we show that two cones over semiregular bipartite graphs are cospectral if and only if they have the same Ihara zeta function. Moreover, the convergence of the zeta function of this family of graphs is considered.
