环状Khovanov同调上的$L_\infty$ -模结构

An $L_\infty$-module Structure on Annular Khovanov Homology

Champ Davis

摘要:

假设$L$是增厚环中的一个环。Grigsby-Licata-Wehrli证明了$L$的环状Khovanov同调具有$sl_2(\wedge)$的作用,这是李代数$sl_2$的外流代数。本文将这一结果推广到$L_\infty$ -代数和模的情形。也就是说,我们证明了$sl_2(\wedge)$是一个$L_\infty$ -代数,并且$L$的环状Khovanov同调是$sl_2(\wedge)$上的一个$L_\infty$ -模.直到$L_\infty$ -拟同构,该结构在Reidemeister移动下是不变的。最后,我们包含了计算更高级别的$L_\infty$运算的显式公式。

英文摘要:

Let $L$ be a link in a thickened annulus. Grigsby-Licata-Wehrli showed that the annular Khovanov homology of $L$ is equipped with an action of $sl_2(\wedge)$, the exterior current algebra of the Lie algebra $sl_2$. In this paper, we upgrade this result to the setting of $L_\infty$-algebras and modules. That is, we show that $sl_2(\wedge)$ is an $L_\infty$-algebra and that the annular Khovanov homology of $L$ is an $L_\infty$-module over $sl_2(\wedge)$. Up to $L_\infty$-quasi-isomorphism, this structure is invariant under Reidemeister moves. Finally, we include explicit formulas to compute the higher $L_\infty$-operations.
