本文证明在带边界几何对偶的光滑可定向4流形中,整洁曲面的拓扑同痕蕴含光滑同痕,从而建立光滑与拓扑同痕类间的双射。
AI 中文摘要
我们证明,在光滑可定向4流形中,对于具有共同非空边界的整洁曲面,若边界中存在几何对偶,则拓扑同痕蕴含光滑同痕。结合我们先前关于曲面光滑化的工作,这表明此类具有给定边界的曲面从光滑同痕类到拓扑同痕类的自然映射是双射。
英文摘要
We prove that topological isotopy implies smooth isotopy for neat surfaces with common nonempty boundary in a smooth orientable 4-manifold, in the presence of a geometric dual in the boundary. Together with our earlier work on surface smoothing, this shows that the natural map from smooth isotopy classes to topological isotopy classes of such surfaces with prescribed boundary is bijective.
