报告摘要:In this talk, I will give a brief introduction of the finite group actions on orientable closed surfaces that can extend to the 3-dimensional sphere. Actions realizing the maximum orders can be determined. They are naturally related to equivariant minimal surfaces in the 3-sphere. These are joint works with Sheng Bai, Shicheng Wang, Yimu Zhang and Bruno Zimmermann.
