论文摘要
在本文中，接触$（+1）$的足够条件 - 沿Legendrian结的手术3秒，以消失的接触不变性或被淘汰。它们可以应用于标准联系人3-Sphere中的Legendrian链接沿Legendrian链接沿Legendrian链接进行研究的联系$（\ pm1）$。我们还获得了足够的条件，可以在标准联系人3-Sphere中沿Legendrian两组分链路进行联系$（+1）$ - 手术，可以通过其前投影限制。
In this paper, sufficient conditions for contact $(+1)$-surgeries along Legendrian knots in contact rational homology 3-spheres to have vanishing contact invariants or to be overtwisted are given. They can be applied to study contact $(\pm1)$-surgeries along Legendrian links in the standard contact 3-sphere. We also obtain a sufficient condition for contact $(+1)$-surgeries along Legendrian two-component links in the standard contact 3-sphere to be overtwisted via their front projections.
