我们引入绞理论技术来计算对应于琼斯多项式的R-矩阵的Yang-Baxter(YB)同调群和上同调群。更具体地说,我们证明了Jones的YB算子R,对同调归一化,允许一个skein分解R= I+ β α,其中α:V 2→ k是一个“杯”配对映射,β:k→ V 2是一个“帽”配对映射,并且与R相关的链复形中的微分可以分解为杯和帽的水平张量级联。我们应用我们的绞理论的方法来确定第二和第三YB同调群,证实了一个猜想Przytycki和王。此外,我们计算R的上同调群,并提供计算在更高的维度,产生一些零化子模。
We introduce skein theoretic techniques to compute the Yang-Baxter (YB) homology and cohomology groups of the R-matrix corresponding to the Jones polynomial. More specifically, we show that the YB operator R for Jones, normalized for homology, admits a skein decomposition R= I+ β α, where α: V⊗ 2→ k is a “cup” pairing map and β: k→ V⊗ 2 is a “cap” copairing map, and differentials in the chain complex associated to R can be decomposed into horizontal tensor concatenations of cups and caps. We apply our skein theoretic approach to determine the second and third YB homology groups, confirming a conjecture of Przytycki and Wang. Further, we compute the cohomology groups of R, and provide computations in higher dimensions that yield some annihilations of submodules.
