Let $G$ be a split semisimple algebraic group over a field and let $A^*$ be an oriented cohomology theory in the Levine–Morel sense. We provide a uniform approach to the $A^*$-motives of geometrically cellular smooth projective $G$-varieties based on the Hopf algebra structure of $A^*(G)$. Using this approach, we provide various applications to the structure of motives of twisted flag varieties.

霍普理论方法研究扭曲国旗品种的动机

假设$ G $是一个域上的一个分裂的半简单代数群,并且让$ A ^ * $是一个在莱文-莫雷尔意义上的定向同调理论。我们基于$ A ^ *(G)$的Hopf代数结构,几何细胞平滑投影$ G $-变量的$ A ^ * $动机提供了统一的方法。使用这种方法,我们为扭曲标志品种的动机结构提供了各种应用程序。
