二重点手术与曲面构形

Double point surgery and configurations of surfaces

Hee Jung Kim, Daniel Ruberman

摘要:

本文在四维流形的浸入曲面上引入了一种新的操作--二重点操作,并利用它构造了许多四维流形中曲面的纽结构形。以分支覆盖为例,我们在具有复杂不动点集的单连通4-流形上产生了Z/mxZ/n的光滑奇异作用。

英文摘要:

We introduce a new operation, double point surgery, on immersed surfaces in a 4-manifold, and use it to construct knotted configurations of surfaces in many 4-manifolds. Taking branched covers, we produce smoothly exotic actions of Z/m x Z/n on simply connected 4-manifolds with complicated fixed-point sets.
