定义了图的二元Bartholdi zeta函数和二元Bartholdi -函数,并给出了它们的行列式表达式.给出了上正则覆盖的多元Bartholdi zeta函数的分解公式.此外,我们表示G的正则覆盖的-变量Bartholdi zeta函数作为其-变量Bartholdi L-函数的产品。
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.
