具有$\mathbb{Z}$作用的图的Zeta函数

Zeta functions of graphs with $\mathbb{Z}$ actions

Bryan Clair

摘要:

设$Y$是图$X$的一个正则覆盖,其覆盖变换群为$π= \mathbb{Z}$ .本文给出了$Y$的$L^2$ zeta函数的显式表达式,并给出了计算实例。当为$π= \mathbb{Z}$时,$L^2$ zeta函数为代数函数。作为结果,它扩展到一个亚纯函数上的黎曼曲面。亚纯扩张提供了一个设置,推广已知的正则图的zeta函数的性质,如奇点的位置和函数方程。

英文摘要:

Suppose $Y$ is a regular covering of a graph $X$ with covering transformation group $π= \mathbb{Z}$. This paper gives an explicit formula for the $L^2$ zeta function of $Y$ and computes examples. When $π= \mathbb{Z}$, the $L^2$ zeta function is an algebraic function. As a consequence it extends to a meromorphic function on a Riemann surface. The meromorphic extension provides a setting to generalize known properties of zeta functions of regular graphs, such as the location of singularities and the functional equation.
