本文给出了具有负欧拉特征的共形有限Riemann曲面的Ricci流一致化的一个新证明。具体来说,我们将考虑完备曲面(M,g 0)上的归一化里奇流<$gij <$t = −(R-r)gij,其中M = N <$L1· · ·<$Lk,N是紧致流形,L1,. . .,Lk是双曲端点。此外,每个(Li,g 0)都渐近接近双曲尖点,即常曲率为−1的度量。我们证明了流g(t)指数收敛于常负曲率度量(−1)。
In this paper we give a new proof of the uniformization of conformally finite Riemann surface of negative Euler characteristic by the Ricci flow. Specifically, we will consider the normalized Ricci flow ∂gij ∂t = −(R− r)gij on a complete surface (M, g0) where M = N∪L1 · · ·∪Lk, N is a compact manifold and L1, . . . , Lk are the hyperbolic ends. Moreover, each (Li, g0) is asymptotically close to the hyperbolic cusp, a metric of constant curvature −1. We prove that the flow g(t) exponentially converges to the metric of constant negative curvature (−1).
