维数小于6的不可约向量值模形式

Irreducible vector-valued modular forms of dimension less than six

Christopher Marks

摘要:

本文对维数小于6的全纯向量值模形式空间和与全模群的不可约、T-可么正化表示有关的乘子系给出了代数分类。对于维数小于4的表示,证明了向量值模形式的相关空间是某个微分算子的斜多项式环上的循环模.对于4维和5维,利用向量值模形式空间是满模群的经典模形式环上的自由模这一事实,给出了可能的希尔伯特-庞加莱级数的完整列表.一个温和的限制,然后放置在这些方面考虑的代表类,这再次产生一个明确的确定相关的希尔伯特-庞加莱级数。

英文摘要:

An algebraic classification is given for spaces of holomorphic vector-valued modular forms of arbitrary real weight and multiplier system, associated to irreducible, T-unitarizable representations of the full modular group, of dimension less than six. For representations of dimension less than four, it is shown that the associated space of vector-valued modular forms is a cyclic module over a certain skew polynomial ring of differential operators. For dimensions four and five, a complete list of possible Hilbert-Poincare series is given, using the fact that the space of vector-valued modular forms is a free module over the ring of classical modular forms for the full modular group. A mild restriction is then placed on the class of representation considered in these dimensions, and this again yields an explicit determination of the associated Hilbert-Poincare series.
