报告摘要: It is known that every finite group action on a closed surface can extend over some m-dimensional sphere via an equivariant embedding. So it is natural to ask what is the minimum possible dimension for a given action. I will discuss some results about this question, and mainly focus on two cases, where the minimum dimension is three or the group action is cyclic.
