The character of ideal circle patterns

Chang Li, Aijin Lin, Liangming Shen

Let $S$ be an oriented closed surface with a cellular decomposition $D$ and a weight $I^¦ \in (0, I ¨ )$ . It is crucial to determine when $S$ supports an ideal $D$ -t…

Improved explicit estimates for the discrete Laplace operator with hyperbolic circle patterns

Aijin Lin, Longxiang Wu

Ge in his thesis \cite{Ge-thesis} introduced the combinatorial Calabi flows and established the long time existence and convergence of solutions to the flows in both hyperbolic and…

Branched $I^\pm$ -combinatorial Ricci flows on closed surfaces with Euler characteristic $I ¨ \leq 0$

Wenjun Li, Rongyuan Liu, Guohao Chen +1

In this paper we introduce the branched $I^\pm$ -flows on closed surfaces with Euler characteristic $Ï\leq 0$. Based on the strict convexity of the branched $I^\pm$ -potentials, we esta…
