组合纽结接触同调与横纽结

Combinatorial knot contact homology and transverse knots

Lenhard Ng

摘要:

我们给出了横同调的一种组合处理方法,横纽结的一个新的不变量是纽结接触同调的推广。该理论有几种形式,其中一种是拓扑结的不变量,并产生一个与A多项式相关的三变量结多项式。我们提供了一些计算的横向同源性,证明其有效性,在区分横向结,包括不能区分的Heegaard Floer横向不变量或其他以前的不变量的结。

英文摘要:

We give a combinatorial treatment of transverse homology, a new invariant of transverse knots that is an extension of knot contact homology. The theory comes in several flavors, including one that is an invariant of topological knots and produces a three-variable knot polynomial related to the A-polynomial. We provide a number of computations of transverse homology that demonstrate its effectiveness in distinguishing transverse knots, including knots that cannot be distinguished by the Heegaard Floer transverse invariants or other previous invariants.
