We define an -variable Bartholdi zeta function and an -variable Bartholdi -function of a graph , and give determinant expressions of them. We present a decomposition formula for the -variable Bartholdi zeta function of a regular covering of . Furthermore, we express the -variable Bartholdi zeta function of a regular covering of G as a product of its -variable Bartholdi L-functions.
