我们从Heegaard Floer同调定义了三维接触结构的一个不变量。该不变量采用集合$\mathbb{Z}_{\geq0}\Cup\{\infty\}$中的值。对于过度扭曲的接触结构,它是零,对于Stein可填充接触结构,它是$\infty$,在Legendrian手术下是不减的,并且可以从任何支持的开卷分解中计算。作为应用,我们讨论了具有非零Ozsvath-Szabo接触类的接触3-流形上的Stein可填充性。
We define an invariant of contact structures in dimension three from Heegaard Floer homology. This invariant takes values in the set $\mathbb{Z}_{\geq0}\cup\{\infty\}$. It is zero for overtwisted contact structures, $\infty$ for Stein fillable contact structures, non-decreasing under Legendrian surgery, and computable from any supporting open book decomposition. As an application, we obstruct Stein fillability on contact 3-manifolds with non-vanishing Ozsvath-Szabo contact class.
