Tangle接触同调

Tangle contact homology

Johan Asplund

AI总结:

本文将knot contact homology扩展为tangle的ambient isotopy不变量,证明了tangle粘合给出相应公式,并得出其能检测tangle平凡性的结论。

摘要:

Knot contact homology是$\mathbb R^3$中纽结与链环的ambient isotopy不变量。本文旨在将此定义扩展为tangle的ambient isotopy不变量,并证明tangle的粘合会给出knot contact homology的粘合公式。作为粘合公式的推论,我们得出tangle contact homology能检测tangle的平凡性。

英文摘要:

Knot contact homology is an ambient isotopy invariant of knots and links in $\mathbb R^3$. The purpose of this paper is to extend this definition to an ambient isotopy invariant of tangles and prove that gluing of tangles gives a gluing formula for knot contact homology. As a consequence of the gluing formula we obtain that the tangle contact homology detects triviality of tangles.
