关于负指数亚纯Jacobi型的傅里叶系数

On the Fourier coefficients of negative index meromorphic Jacobi forms

Kathrin Bringmann, Larry Rolen, Sander Zwegers

摘要:

本文考虑负指数亚纯Jacobi型的傅里叶系数。这扩展了最近的工作Creutzig和前两个作者的特殊情况下,卡茨Wakimoto字符自然发生在李理论,并产量,作为简单的推论,许多重要的偏微分方程产生的组合,如著名的秩曲柄偏微分方程的阿特金和Garvan。此外,我们还讨论了我们的结果与Zagier引入的部分θ函数和量子模形式之间的关系,并与以前关于正指数亚纯Jacobi形式的工作一起阐明了亚纯Jacobi形式的傅里叶系数的一般结构.

英文摘要:

In this paper, we consider the Fourier coefficients of meromorphic Jacobi forms of negative index. This extends recent work of Creutzig and the first two authors for the special case of Kac-Wakimoto characters which occur naturally in Lie theory, and yields, as easy corollaries, many important PDEs arising in combinatorics such as the famous rank-crank PDE of Atkin and Garvan. Moreover, we discuss the relation of our results to partial theta functions and quantum modular forms as introducted by Zagier, which together with previous work on positive index meromorphic Jacobi forms illuminates the general structure of the Fourier coefficients of meromorphic Jacobi forms.
