研究了黎曼曲面上的实投影连接及其对应的Liouville方程的解。我们证明了这些解在有限数量的简单解析轮廓上具有一种特殊类型(黑洞类型)的奇点。我们详细分析了V. I.斯米尔诺夫的论文(彼得格勒,1918)中考虑的具有四个实点的黎曼球的情况。
We consider real projective connections on Riemann surfaces and their corresponding solutions of the Liouville equation. We show that these solutions have singularities of a special type (a black-hole type) on a finite number of simple analytic contours. We analyze the case of the Riemann sphere with four real punctures, considered in V. I. Smirnov’s thesis (Petrograd, 1918) in detail.
