亏格为零的富克斯群的Eisenstein级数的零点

On zeros of Eisenstein series for genus zero Fuchsian groups

Heekyoung Hahn

摘要:

设$\GN\leq\SLR$是第一类亏格为零的Fuchsian群,其中$\infty$为尖点,并设$\Ek$是$\GN$上权$2k$的全纯Eisenstein级数,它在$\infty$处不为零,在所有其他尖点处为零(假设这样的Eisenstein级数存在)。在一定的假设下$\GN,$和一个基本域$\F$的选择,我们证明了所有,但可能$c(\GN,\F)$的非平凡零$\Ek$谎言的某个子集的$\{z\in\mathfrak{H} : \JN(z)\in\mathbb{R}\}$。这里,$c(\GN,\F)$是不依赖于权重$2k$的常数,$\JN$是$\GN.$的规范半模

英文摘要:

Let $\GN\leq\SLR$ be a genus zero Fuchsian group of the first kind with $\infty$ as a cusp, and let $\Ek$ be the holomorphic Eisenstein series of weight $2k$ on $\GN$ that is nonvanishing at $\infty$ and vanishes at all the other cusps (provided that such an Eisenstein series exists). Under certain assumptions on $\GN,$ and on a choice of a fundamental domain $\F$, we prove that all but possibly $c(\GN,\F)$ of the non-trivial zeros of $\Ek$ lie on a certain subset of $\{z\in\mathfrak{H} : \JN(z)\in\mathbb{R}\}$. Here $c(\GN,\F)$ is a constant that does not depend on the weight $2k$ and $\JN$ is the canonical hauptmodul for $\GN.$
