亏格为2且具有最简divisor的Siegel模形式

The Siegel modular forms of genus 2 with the simplest divisor

Valery Gritsenko, Fabien Clery

摘要:

证明了亏格为2的仿模群的Hecke型同余子群沿Siegel上半平面的对角线精确为零的Siegel模形式存在8个.这是在“黑洞、黑环和模形式“会议(ENS,巴黎,2007年8月)期间提出的一个问题的解决方案。这些模形式推广了经典的Igusa形式和Gritsenko和Nikulin在1998年构造的形式。

英文摘要:

We prove that there exist exactly eight Siegel modular forms with respect to the congruence subgroups of Hecke type of the paramodular groups of genus two vanishing precisely along the diagonal of the Siegel upper half-plane. This is a solution of a question formulated during the conference "Black holes, Black Rings and Modular Forms" (ENS, Paris, August 2007). These modular forms generalize the classical Igusa form and the forms constructed by Gritsenko and Nikulin in 1998.
