摘要:

HCMU度量是一种在Riemann面上带奇点的extremal度量. 它可以被一个亚纯1-形式所刻划. 文章给出这个亚纯1-形式的一些重要性质. 作为应用,将证明一个HCMU度量的高斯曲率光滑的充要条件.

关键词: extremal度量, HCMU度量, 特征1-形式

Abstract:

An HCMU metric is a kind of extremal metric with conical singularities on a Riemann surface. It can be characterized by a meromorphic 1-form. In this paper we give some important properties of this meromorphic 1-form. As an application we prove the sufficient and necessary condition of the Gauss curvature of an HCMU metric being smooth.

Key words: extremal metric, HCMU metric, character 1-form
