摘 要:This is a survey talk mostly occupied by intuitive examples and figures, and the methods will be mentioned. Suppose a finite group G acts on F_g, the surface of genus g. The talk will consists of three parts.
(1) We first consider how to extend to the G action over the 3-sphere for some embedding form F_g to the 3-sphere. (jointly with C. Wang, B. Zimmermann, Y. Zhang).
