有限体积复双曲曲面,它们的环面紧化及其几何应用

Finite volume complex-hyperbolic surfaces, their toroidal compactifications, and geometric applications

Luca Fabrizio Di Cerbo

摘要:

本文研究了Kodaira和Enriques意义下的非均匀球代数的光滑环面紧化的分类。此外,还给出了关于这些空间的黎曼几何和复代数几何的一些结果。特别是,我们证明了存在紧致复曲面,它们允许非正曲率的黎曼度量,但不允许非正曲率的凯勒度量。一个无限类的这样的例子出现作为光滑环面紧化的球等价物。

英文摘要:

We study the classification of smooth toroidal compactifications of nonuniform ball quotients in the sense of Kodaira and Enriques. Moreover, several results concerning the Riemannian and complex algebraic geometry of these spaces are given. In particular we show that there are compact complex surfaces which admit Riemannian metrics of nonpositive curvature, but which do not admit Kähler metrics of nonpositive curvature. An infinite class of such examples arise as smooth toroidal compactifications of ball quotients.
