Abstract
Let \(G=H[G_1,G_2,\ldots ,G_k]\) be the generalized join graph of\(G_1,G_2,\ldots ,G_k\) determined by H. In this paper, we give a decomposition formula for the Bartholdi zeta function of G. As applications, we obtain explicit formulae for Bartholdi zeta functions of some special kinds of graphs, such as the complete multipartite graph, the wheel, etc.
