使用非半简单 Temperley-Lieb 微积分,我们研究了混合情况下 $$ extrm{SL}_{2}$$ SL 2 倾斜模块类别的加法和幺半结构。这同时概括了半简单情况、单位根处的复量子群的情况以及正特性的代数群情况。我们描述了特征公式,并通过带有关系的箭袋将倾斜模块的类别表示为附加类别。转向幺半群结构,我们描述融合规则并获得琼斯-温兹尔投影仪的适当模拟的显式递归描述。
Using the non-semisimple Temperley–Lieb calculus, we study the additive and monoidal structure of the category of tilting modules for $$ extrm{SL}_{2}$$ SL 2 in the mixed case. This simultaneously generalizes the semisimple situation, the case of the complex quantum group at a root of unity, and the algebraic group case in positive characteristic. We describe character formulas and give a presentation of the category of tilting modules as an additive category via a quiver with relations. Turning to the monoidal structure, we describe fusion rules and obtain an explicit recursive description of the appropriate analog of Jones–Wenzl projectors.
