AI总结:

研究了标准接触3球体中沿横结的Cosmetic接触手术,证明了非平凡手术的排除,并展示了横结由外皮接触同构类型确定的结论。

摘要:

我们研究在标准接触3球体中沿横结进行的 Cosmetic 接触手术,即那些再次得到标准接触3球体的接触手术。主要结果是,我们可以排除所有非平凡的 Cosmetic 接触手术,这些横结不与自链接数为-1的横无结同伦。作为推论,得出每个标准接触3球体中的横结由其外皮的接触同构类型确定。此外,我们给出了在标准接触3球体中横链的反例。

英文摘要:

We study cosmetic contact surgeries along transverse knots in the standard contact 3-sphere, i.e. contact surgeries that yield again the standard contact 3-sphere. The main result is that we can exclude non-trivial cosmetic contact surgeries along all transverse knots not isotopic to the transverse unknot with self-linking number -1. As a corollary it follows that every transverse knot in the standard contact 3-sphere is determined by the contactomorphism type of its exteriors. Moreover, we give counterexamples to this for transverse links in the standard contact 3-sphere.
