通过辫子计算透镜空间$L(p,1)$的HOMFLYPT扭模的一个重要步骤

An important step for the computation of the HOMFLYPT skein module of the lens spaces $L(p,1)$ via braids

Ioannis Diamantis, Sofia Lambropoulou

摘要:

我们证明,为了从固体环面的HOMFLYPT绞链模$\mathcal{S}({\rm ST})$导出透镜空间$L(p,1)$的HOMFLYPT绞链模,只需求解通过对固体环面中的结和链施加Lambropoulou不变量$X$而获得的无限方程组,仅在集合$Λ^{aug}$中的第一移动元素链上执行的编织带移动,扩充$\mathcal{S}({\rm ST})$的基础$Λ$。

英文摘要:

We prove that, in order to derive the HOMFLYPT skein module of the lens spaces $L(p,1)$ from the HOMFLYPT skein module of the solid torus, $\mathcal{S}({\rm ST})$, it suffices to solve an infinite system of equations obtained by imposing on the Lambropoulou invariant $X$ for knots and links in the solid torus, braid band moves that are performed only on the first moving strand of elements in a set $Λ^{aug}$, augmenting the basis $Λ$ of $\mathcal{S}({\rm ST})$.
