$\mathbb{R}P^3$的Kauffman括号串模的分类

The categorification of the Kauffman bracket skein module of $\mathbb{R}P^3$

Boštjan Gabrovšek

摘要:

Khovanov同调是$\mathbb{R}^3$中链的不变量,它是一种分次同调理论,在同调的分次欧拉示性数是琼斯多项式的意义上,它对琼斯多项式进行了分类。Asaeda,Przytycki和Sikora通过定义一个双阶同调理论来推广这个构造,该理论将曲面上的$I$ -丛中的链的Kauffman括号skein模分类,除了曲面$\mathbb{R}P^2$,在曲面上,当投影到不可定向曲面$\mathbb{R}P^2$时,由于链的奇怪行为,构造失败。本文通过重新定义Khovanov链复形中的微分,对$\mathbb{R}P^2$上的扭曲$I$ -丛的缺失情形进行了分类,即$\mathbb{R}P^2$ \widetilde{\times} I \approx \rpt \setminus \{ \ast \}$.

英文摘要:

Khovanov homology, an invariant of links in $\mathbb{R}^3$, is a graded homology theory that categorifies the Jones polynomial in the sense that the graded Euler characteristic of the homology is the Jones polynomial. Asaeda, Przytycki and Sikora generalized this construction by defining a double graded homology theory that categorifies the Kauffman bracket skein module of links in $I$-bundles over surfaces, except for the surface $\mathbb{R}P^2$, where the construction fails due to strange behaviour of links when projected to the non-orientable surface $\mathbb{R}P^2$. This paper categorifies the missing case of the twisted $I$-bundle over $\mathbb{R}P^2$, $\mathbb{R}P^2$ \widetilde{\times} I \approx \rpt \setminus \{\ast\}$, by redefining the differential in the Khovanov chain complex in a suitable manner.
