正交Shimura簇的模形式空间的Toroidal紧化和维数公式

Toroidal Compactifications and Dimension Formulas for Spaces of Modular Forms for Orthogonal Shimura Varieties

Andrew Fiori

摘要:

本文描述了构造局部对称空间的环面紧化的一般理论,并利用这些理论计算了模形式空间的维数公式。我们重点明确的情况下,正交的局部对称空间所产生的二次型的签名$(2,n)$,给出明确的细节的建设,结构和结果,在这些情况下。这篇文章没有给出显式的锥分解,计算显式的相交配对,或计数尖点,因此没有给出任何完整的维数公式。这篇文章仍在“修订中”。

英文摘要:

In this paper we describe the general theory of constructing toroidal compactifications of locally symmetric spaces and using these to compute dimension formulas for spaces of modular forms. We focus explicitly on the case of the orthogonal locally symmetric spaces arising from quadratic forms of signature $(2,n)$, giving explicit details of the constructions, structures and results in these cases. This article does not give explicit cone decompositions, compute explicit intersection pairings, or count cusps and thus does not give any complete formulas for the dimensions. This article is still `in preparation'.
