带符号向量的弱全纯模形式的整除性质

Divisibility properties for weakly holomorphic modular forms with sign vectors

Yichao Zhang

摘要:

本文证明了符号向量的约化模形式的傅里叶系数的可除性结果。更准确地说,我们推广了Siegel关于常数项的整除性结果,当权为非正时,这与Borcherds的权为零时的提升有关。通过考虑带符号向量的弱全纯模形式空间的Hecke算子,得到了约化模形式在“正交”方向上的整除性结果.

英文摘要:

In this paper, we prove some divisibility results for the Fourier coefficients of reduced modular forms of sign vectors. More precisely, we generalize a divisibility result of Siegel on constant terms when the weight is non-positive, which is related to the weight of Borcherds lifts when the weight is zero. By considering Hecke operators for the spaces of weakly holomorphic modular forms with sign vectors, and obtain divisibility results in an "orthogonal" direction on reduced modular forms.
