本文给出了量子旗流形上量子微分算子层的整体截面由量子群给出的定理的一个简短的新证明。作为推论,我们检索约瑟夫和Letzter的量子版本的经典包络代数定理的Duflo和Kostant。我们还描述了量子群的ad-可积部分的中心和它的伴随李代数作用。
We give a short new proof for the theorem that global sections of the sheaf of quantum differential operators on a quantum flag manifold are given by the quantum group. As corollaries we retrieve Joseph and Letzter's quantum versions of classical enveloping algebra theorems of Duflo and Kostant. We also describe the center of the ad-integrable part of the quantum group and the adjoint Lie algebra action on it.
