量子(sl_n,\land V_n)链不变量与矩阵分解

Quantum (sl_n, \land V_n) link invariant and matrix factorizations

Yasuyoshi Yonezawa

摘要:

M. Khovanov和L. Rozansky给出了HOMFLY-PT多项式的分类。本文是Khovanov-Rozansky同调的推广。我们定义了一个与量子$(sl_n,\land V_n)$链接不变量相关的同调,其中$\land V_n$是$sl_n$的量子群的基本表示的集合。在[1,k]-着色链图的情形下,我们证明了它的同调是一个链不变量。在[i,j]-着色链接图的情况下,定义了其同调的归一化Poincare多项式,并证明了该多项式是链接不变量。

英文摘要:

M. Khovanov and L. Rozansky gave a categorification of the HOMFLY-PT polynomial. This study is a generalization of the Khovanov-Rozansky homology. We define a homology associated to the quantum $(sl_n,\land V_n)$ link invariant, where $\land V_n$ is the set of the fundamental representations of the quantum group of $sl_n$. In the case of a [1,k]-colored link diagram, we prove that its homology is a link invariant. In the case of an [i,j]-colored link diagram, we define a normalized Poincare polynomial of its homology and prove the polynomial is a link invariant.
