摘要

在紧致的Calabi-Yau流形上,虚部具有确定惯性指数的周期矩阵形成复空间的子空间.在这些子空间上,对辛群Sp(2n,Z)的子群G0发展了模形式理论, 并在具有一个负惯性指标的周期矩阵所形成的空间上给出了推广的Siegel模形式表达式.

Abstract

We try to present modular form theory defined on the space formed by the entries of period matrices whose imaginary parts have definite signature on compact Calabi-Yau manifolds for the subgroup G0 of Sp(2n,Z). Then some expressions similar to Siegel modular forms are given on the space of period matrices with one negative inertia index.
