摘要

本文的前两部分提供了一个方便的方案和额外的图解，用于处理Frobenius扩展，该扩展负责等变SL（2）链同源理论的关键风格。目的是阐明理论中的一些基本结构，并提出一个在足够非退化的基环上工作的设置。第三部分对接缝表面进行了两个相关的SL（2）评估。

Link homology and Frobenius extensions II

The first two sections of the paper provide a convenient scheme and additional diagrammatics for working with Frobenius extensions responsible for key flavors of equivariant SL(2) link homology theories. The goal is to clarify some basic structures in the theory and propose a setup to work over sufficiently non-degenerate base rings. The third section works out two related SL(2) evaluations for seamed surfaces.
