关于Selberg zeta函数一个特殊值的注记

Remarks on a special value of the Selberg zeta function

Nicolas Templier

摘要:

令$\CmZ_{Y_0(N)}$为模曲线$Y_0(N)$的Selberg zeta函数在$s=1$处的对数导数的常数项。Jorgenson和Kramer通过将其与几何不变量联系起来,建立了约束$\CmZ_{Y_0(N)}=O_ε(N^ε)$、$ε>0$。本文利用$L$ -函数和指数和给出了$N$素数的另一个证明,改进了Abbes-Ullmo和Michel-Ullmo的方法.我们进一步导出了$\log N$在同一直线上的幂。

英文摘要:

Let $\CmZ_{Y_0(N)}$ be the constant term of the logarithmic derivative at $s=1$ of the Selberg zeta function of the modular curve $Y_0(N)$. Jorgenson and Kramer established the bound $\CmZ_{Y_0(N)}=O_ε(N^ε)$, $ε>0$ by relating it to geometric invariants. In this article we give, for $N$ prime, another proof via $L$-functions and exponential sums improving on a previous approach by Abbes-Ullmo and Michel-Ullmo. We further derive a power of $\log N$ bound along the same line.
