链同调与加细拓扑顶点

Link Homologies and the Refined Topological Vertex

Sergei Gukov, Amer Iqbal, Can Kozcaz, Cumrun Vafa

摘要:

建立了Hopf环的sl(N)同调不变量与加细拓扑顶点之间的直接映射,其中Khovanov-Rozansky同调是其特例.这个关系提供了一个确切的答案,为同调不变量的霍普夫链,其组件着色的任意表示sl(N)。目前,这类同调不变量的数学表述仅适用于基本表示(Khovanov-Rozansky理论),与精化拓扑顶点的关系对于分类与其他表示(R_1,R_2)相关的量子群不变量应该是有用的。我们的结果是第一次直接验证的一系列的identures,确定链接同源性与希尔伯特空间的BPS状态在膜的存在下,其中的物理解释的分级是在收费的膜结束拉格朗日膜。

英文摘要:

We establish a direct map between refined topological vertex and sl(N) homological invariants of the of Hopf link, which include Khovanov-Rozansky homology as a special case. This relation provides an exact answer for homological invariants of the of Hopf link, whose components are colored by arbitrary representations of sl(N). At present, the mathematical formulation of such homological invariants is available only for the fundamental representation (the Khovanov-Rozansky theory) and the relation with the refined topological vertex should be useful for categorifying quantum group invariants associated with other representations (R_1, R_2). Our result is a first direct verification of a series of conjectures which identifies link homologies with the Hilbert space of BPS states in the presence of branes, where the physical interpretation of gradings is in terms of charges of the branes ending on Lagrangian branes.
