摘要: 林爱津和张潇潇首次引入组合$p$次Ricci流, 将Chow-Luo关于组合Ricci流$(p=2)$的经典结果推广至任意$p>1$. 然而, 他们在欧几里得背景几何中的推广并不完整: 仅证明了离散曲率沿该流的收敛性, 未能建立圆填充度量的收敛性. 本文 通过引入一个依赖于时间的规范项$C(t)$, 克服了组合$p$次Ricci流解缺乏紧性所带来的核心障碍. 我们的结果改进了林爱津和张潇潇的相应结论, 并以完全一般性的方式将Chow-Luo在欧几里得背景几何中的经典结果从$p=2$推广至任意$p>1$.

Abstract: Lin and Zhang first introduced the combinatorial $p$-th Ricci flows and generalized Chow-Luo's classical results on combinatorial Ricci flows (when $p=2$) to any $p>1$. However, their generalization in Euclidean background geometry is incomplete: they only proved the convergence of discrete curvatures along the flow, but failed to establish the convergence of circle packing metrics. In this paper, by introducing a time-dependent normalization term $C(t)$, we overcome the core obstacle arising from the lack of compactness for solutions to combinatorial $p$-th Ricci flows. Our results improve those of Lin and Zhang and generalize Chow-Luo's classical results in Euclidean background geometry from $p=2$ to any $p>1$ in full generality.
