曲面的广义Skein模

Generalized Skein Modules of Surfaces

Jeffrey Boerner, Paul Drube

摘要:

弗罗贝纽斯扩张在基于sl(n)链变体的链同调论中起着核心作用,并且这些弗罗贝纽斯扩张中的每一个都可以以Bar-Natan的方式通过一类有标记的配边进行几何重铸。在这里,我们探讨了一个大的家庭,这样的标记配边范畴是相关的广义sl(n)链接同调论。我们还调查了绞链模块,结果从嵌入这些标记的协边3流形,并在这些广义绞链模块的几个明确的介绍。

英文摘要:

Frobenius extensions play a central role in the link homology theories based upon the sl(n) link variants, and each of these Frobenius extensions may be recast geometrically via a category of marked cobordisms in the manner of Bar-Natan. Here we explore a large family of such marked cobordism categories that are relevant to generalized sl(n) link homology theories. We also investigate the skein modules that result from embedding these marked cobordisms within 3-manifolds, and arrive at an explicit presentation for several of these generalized skein modules.
