拟Jacobi型的同余子群和Taylor系数的Bloch-Okounkov定理

The Bloch-Okounkov theorem for congruence subgroups and Taylor coefficients of quasi-Jacobi forms

Jan-Willem M. van Ittersum

摘要:

有许多函数族在划分上,例如移位对称函数,其对应的q括号是拟模形式。我们扩展这些家庭,使相应的q括号是拟模的同余子群。此外,我们发现这些家庭的子空间的q括号是一个模形式。这些结果是由严格亚纯拟Jacobi型在有理格点周围的Taylor系数的性质得到的。

英文摘要:

There are many families of functions on partitions, such as the shifted symmetric functions, for which the corresponding q-brackets are quasimodular forms. We extend these families so that the corresponding q-brackets are quasimodular for a congruence subgroup. Moreover, we find subspaces of these families for which the q-bracket is a modular form. These results follow from the properties of Taylor coefficients of strictly meromorphic quasi-Jacobi forms around rational lattice points.
