q-W代数的结构

The structure of q-W algebras

A. Sevostyanov

摘要:

本文给出了Poisson q-W代数的两种描述,Poisson q-W代数是复半单李代数g中伴随轨道的Slodowy横截片在某些代数群上的正则函数的Poisson代数.为了获得第一个描述,我们引入某些投影算子,它们类似于所谓的Zhelobenko和极值投影算子的准经典版本。作为副产品,我们得到了代数群中Bruhat胞腔上自然坐标的一些新公式。

英文摘要:

We suggest two explicit descriptions of the Poisson q-W algebras which are Poisson algebras of regular functions on certain algebraic group analogues of the Slodowy transversal slices to adjoint orbits in a complex semisimple Lie algebra g. To obtain the first description we introduce certain projection operators which are analogous to the quasi-classical versions of the so-called Zhelobenko and extremal projection operators. As a byproduct we obtain some new formulas for natural coordinates on Bruhat cells in algebraic groups.
