摘要:The Ricci flow was introduced by Hamilton and used by Perelman for the proof of the Poincaré conjecture. Chow and Luo introduced an analogous combinatorial Ricci flows and gave a new proof of Thurston’s existence of circle packing theorem. Since then, combinatorial Ricci flow has been broadly applied by Gu et al. in many important problems, such as parameterization in graphics, and cancer detection in medical imaging. In this talk, we will discuss related problems and our work on the combinatorial Ricci flows.
