$K^G(\mathcal{B} \times \mathcal{B})$上的卷积代数结构

The convolution algebra structure on $K^G(\mathcal{B} \times \mathcal{B})$

Sian Nie

摘要:

证明了卷积代数$K^G(\mathcal{B} \times \mathcal{B})$同构于与$G$相关的扩展仿射外尔群的最低双边胞腔的Based环,其中$G$是复数域$\mathbb{C}$上的连通约化代数群,$\mathcal{B}$是$G$的旗簇.

英文摘要:

We show that the convolution algebra $K^G(\mathcal{B} \times \mathcal{B})$ is isomorphic to the Based ring of the lowest two-sided cell of the extended affine Weyl group associated to $G$, where $G$ is a connected reductive algebraic group over the field $\mathbb{C}$ of complex numbers and $\mathcal{B}$ is the flag variety of $G$.
