内容摘要：Ring Lemma is an essential lemma controlling the geometric  properties of univalent circle packings.  Inspired by a Ring Lemma proved by Zhengxu He, we introduced a way to generalize the Ring Lemma to the case of ideal circle patterns. In this talk, I will present how the Ring Lemma holds, and is used to prove the existence of infinite ideal circle patterns embedded on the plane. This talk is from the joint work of Huabin Ge and Hao Yu.

报告人简历：Puchun Zhou is currently a postdoc at Oxford University. He obtained his Ph.D. at Fudan University under the supervision of Bobo Hua. His research focuses on Circle Packing and Discrete Geometry.
