高阶Maass形式

Higher order Maass forms

Roelof Bruggeman, Nikolaos Diamantis

摘要:

本文确定了PSL(2,R)中具有尖点的余有限离散子群的偶权高阶Maass型空间的大小。如果允许顶点处的指数增长性,则给定阶的马斯形式的空间是代数约束所允许的最大空间。我们证明了全纯形式空间的类似陈述。对于PSL(2,R)的泛覆叠群上的函数,我们引入了广义权的概念.对于具有偶数广义权的高阶Maass形式的空间,我们证明了其大小是最大的。

英文摘要:

We determine the size of spaces of higher order Maass forms of even weight for cofinite discrete subgroups of PSL(2,R) with cusps. If exponential growth at the cusps is allowed, the spaces of Maass forms of a given order are as large as algebraic constrictions allow. We show the analogous statement for the spaces of holomorphic forms. For functions on the universal covering group of PSL(2,R) we introduce the concept of generalized weight. For the resulting spaces of higher order Maass forms with even generalized weight we show that the size is maximal.
