Maximum Orders of Extendable Actions on surfaces
收藏 引用
Acta Mathematica Sinica,English Series 2016年 第1期32卷 54-68页
作者: Chao WANG Shi Cheng WANG Yi Mu ZHANG School of Mathematical Sciences Peking University
We determine the maximum order Eg of finite groups G acting on the closed surface E9 of genus g which extends over (S3, ∑g) for all possible embeddings ∑g → S3, where g 〉 1.

Embedding Periodic Maps on surfaces into Those on S^3
收藏 引用
Chinese Annals of Mathematics,Series B 2015年 第2期36卷 161-180页
作者: Yu GUO Chao WANG Shicheng WANG Yimu ZHANG School of Mathematical Sciences Peking University
Call a periodic map h on the closed orientable surface Σg extendable if h extends to a periodic map over the pair(S3, Σg) for possible embeddings e : Σg→ S3. The authors determine the extendabilities for all perio... 详细信息

The symmetries of surfaces which can be embedded into the symmetries of the 3-dimensional Euclidean space R3 are easier to feel by human's intuition. We give the maximum order of finite group actions on (R3 E) amon... 详细信息
