题目: What are discrete spheres? 
报告人:刘世平 (中国科学技术大学)

摘要: In this talk we discuss a discrete version of Bonnet-Myers-Cheng theorem, which involves estimate of graph diameter via discrete curvature bounds and the related rigidity results. This theorem justifies the analogies between strongly spherical grpahs and round spheres. This talk is based on joint works with Cushing, Kamtue, Koolen, Muench and Peyerimhoff.
