关于有理同调球面上的松Legendrian纽结

On loose Legendrian knots in rational homology spheres

Alberto Cavallo

摘要:

证明了有理同调切触3-球面中的松勒让德纽结,满足一些附加的假设,是勒让德同位素当且仅当它们具有相同的经典不变量。证明需要一个结果Dymara松散Legendrian结和Eliashberg的分类overtwisted切触结构上的3流形。

英文摘要:

We prove that loose Legendrian knots in a rational homology contact 3-sphere, satisfying some additional hypothesis, are Legendrian isotopic if and only if they have the same classical invariants. The proof requires a result of Dymara on loose Legendrian knots and Eliashberg's classification of overtwisted contact structures on 3-manifolds.
