Convergence of combinatorial Ricci flows to degenerate circle patterns

Research output: Contribution to journalArticle


We investigate the combinatorial Ricci flow on a surface of nonpositive Euler characteristic when the necessary and sufficient condition for the convergence of the combinatorial Ricci flow is not valid. This observation addresses one of the questions raised by B. Chow and F. Luo.
