Crossingless matchings and the cohomology of (n,n) Springer varieties
摘要：
在数学QA/0103190中引入的环序列$H^n, n\ge 0,$控制缠结的量子sl（2）不变量的分类。证明了$H^n$的中心同构于（n，n）Springer簇的上同调环，并证明了$H^n$ -模的导出范畴中的辫群作用下降到对称群的Springer作用.
英文摘要：
The sequence of rings $H^n, n\ge 0,$ introduced in math.QA/0103190, controls categorification of the quantum sl(2) invariant of tangles. We prove that the center of $H^n$ is isomorphic to the cohomology ring of the (n,n) Springer variety and show that the braid group action in the derived category of $H^n$-modules descends to the Springer action of the symmetric group.
