线缆连接和L空间手术

Cable links and L-space surgeries

Eugene Gorsky, Jennifer Hom

摘要:

L-空间链接是$S^3$中的链接,其上所有足够大的积分手术都是L-空间。证明了当m,n互素时,r-分量链$K_{rm,rn}$是L-空间链当且仅当K是L-空间纽结且$n/m \geq 2g(K)-1$ .我们还计算了L-空间电缆链路的HFL-减和HFL-帽的亚历山大多项式。作为一个应用,我们证实了Licata关于(n,n)环面链的HFL-hat结构的一个猜想。

英文摘要:

An L-space link is a link in $S^3$ on which all sufficiently large integral surgeries are L-spaces. We prove that for m, n relatively prime, the r-component cable link $K_{rm,rn}$ is an L-space link if and only if K is an L-space knot and $n/m \geq 2g(K)-1$. We also compute HFL-minus and HFL-hat of an L-space cable link in terms of its Alexander polynomial. As an application, we confirm a conjecture of Licata regarding the structure of HFL-hat for (n,n) torus links.
