摘要

利用1-扭转边缘手术，我们构造了无限多个平滑嵌入的可定向表面，这些表面在3球中有一个结，它们是成对拓扑同位素的，但不是环境微分同构的。我们利用它们在微扰缝合线花同源上诱导的映射来区分曲面。在此过程中，我们证明了韦恩斯坦协协中由上升曲面诱导的协协映射保留了结花同调中的横向不变量。

Transverse invariants and exotic surfaces in the 4–ball

Using 1-twist rim surgery, we construct infinitely many smoothly embedded, orientable surfaces in the 4-ball bounding a knot in the 3-sphere that are pairwise topologically isotopic, but not ambient diffeomorphic. We distinguish the surfaces using the maps they induce on perturbed sutured Floer homology. Along the way, we show that the cobordism map induced by an ascending surface in a Weinstein cobordism preserves the transverse invariant in knot Floer homology.
