Hall categories and KLR categorification

Adam Gal, Elena Gal, Kobi Kremnizer

摘要:

本文是利用几何和Hall代数对量子群$U_{q}(\mathfrak{g})$的半个上的双代数结构进行分类的第一步。我们用稳定的$\infty$范畴中的代数对象的结构来装备一个D-模范畴在一个D-模范畴的表示范畴$Rep_{\mathbb{C}}(Q)$的对象的模栈上。这个结构的数据是由Waldhausen结构在$Rep_{\mathbb{C}}(Q)$类中的扩展提供的。我们讨论了与量子群$Q$相关的量子群$U_{q}(\mathfrak{g})$的Khovanov-Lauda-Rouquier分类的连接,并概述了我们对双代数结构进行分类的方法。

英文摘要:

This paper is the first step in the project of categorifying the bialgebra structure on the half of quantum group $U_{q}(\mathfrak{g})$ by using geometry and Hall algebras. We equip the category of D-modules on the moduli stack of objects of the category $Rep_{\mathbb{C}}(Q)$ of representations of a quiver with the structure of an algebra object in the category of stable $\infty$-categories. The data for this construction is provided by an extension of the Waldhausen construction for the category $Rep_{\mathbb{C}}(Q)$. We discuss the connection to the Khovanov-Lauda-Rouquier categorification of half of the quantum group $U_{q}(\mathfrak{g})$ associated to the quiver $Q$ and outline our approach to the categorification of the bialgebra structure.
