关于辛帽

On symplectic caps

David T. Gay, Andras I. Stipsicz

摘要:

一类重要的接触3-流形是那些出现的理性表面奇点减少基本周期的链接。我们明确地描述辛帽(凹填充),这样的接触3-流形。作为一个应用,我们提出了一个新的障碍,这样的奇点,承认合理的同调盘光滑。

英文摘要:

An important class of contact 3--manifolds are those that arise as links of rational surface singularities with reduced fundamental cycle. We explicitly describe symplectic caps (concave fillings) of such contact 3--manifolds. As an application, we present a new obstruction for such singularities to admit rational homology disk smoothings.
