摘要
在Hu et al.(2025)中,他们研究了一种广义双曲圆填充(包括圆、圆圆和超圆),在这种圆填充的每个广义圆上都有一个总测地线曲率,在每个对偶圆的中心上有一个离散高斯曲率。本文引入组合Ricci流和组合Calabi流,对包含规定的广义圆总测地线曲率和双圆盘中心上的离散高斯曲率的数据求出这类广义圆填充。证明了双曲几何中具有给定初值的组合Ricci流和组合Calabi流的解一直存在,并以指数速度收敛到一个唯一的广义圆填充度量。
Combinatorial Ricci flow and Calabi flow for generalized hyperbolic circle packings
In Hu et al. (2025), they studied a generalized hyperbolic circle packing (including circles, horocycles and hypercycles) with a total geodesic curvature on each generalized circle of this circle packing and a discrete Gaussian curvature on the center of each dual circle. In this paper, we introduce the combinatorial Ricci flow and combinatorial Calabi flow to find this type of generalized circle packings for a data including prescribed total geodesic curvatures of generalize circles and discrete Gaussian curvatures on centers of dual disks. We show that the solution to the combinatorial Ricci flow and combinatorial Calabi flow in the hyperbolic geometry with the given initial value exists for all the time and converges exponentially fast to a unique generalized circle packing metric.
