在本文中,我们介绍多面体卡勒流形的概念,甚至是具有酉完整的维多面体流形。我们专注于 4 维情况,证明此类流形是光滑的复表面,并对度量的奇点进行分类。奇点形成一个除数,并且除数的补数上的平坦连接的留数给我们一个上同调方程组。 T. Mochizuki 的 Kobayshi-Hitchin 对应的抛物线版本允许我们用复杂线排列的奇点来表征 CP^2 上非负曲率的多面体卡勒度量。
In this article we introduce the notion of Polyhedral Kahler manifolds, even dimensional polyhedral manifolds with unitary holonomy. We concentrate on the 4-dimensional case, prove that such manifolds are smooth complex surfaces, and classify the singularities of the metric. The singularities form a divisor and the residues of the flat connection on the complement of the divisor give us a system of cohomological equations. Parabolic version of Kobayshi-Hitchin correspondence of T. Mochizuki permits us to characterize polyhedral Kahler metrics of non-negative curvature on CP^2 with singularities at complex line arrangements.
