本文建立了具有特定边界曲线系统的实体环面的Bar-Natan skein模与(n, n)施普林格变体的同构性。这些结果建立在Khovanov的无交叉匹配和(n, n)施普林格的上同调的基础上。对于这种特殊的三流形和边界曲线系统,我们还给出了Bar-Natan skein模块中的乘法公式。
This paper establishes an isomorphism between the Bar-Natan skein module of the solid torus with a particular boundary curve system and the homology of the (n, n) Springer variety. The results build on Khovanov’s work with crossingless matchings and the cohomology of the (n, n) Springer variety. We also give a formula for comultiplication in the Bar-Natan skein module for this specific three-manifold and boundary curve system.
