编织双打

Braided doubles

Yuri Bazlov, Arkady Berenstein

摘要:

辫子双为经典和量子泛包络代数和有理切雷德尼克代数提供了一个统一的框架。它们是一类具有三角分解的代数,产生于变形问题,其解称为拟Yetter-Drinfeld模。准YD模的一个基本族是由辫子(满足量子杨-巴克斯特方程的矩阵)提供的;这些产生了量子形式的外尔代数,其中多项式环的作用由尼科尔斯-沃罗诺维奇代数扮演。t = 0的有理切雷德尼克代数作为Nichols-Woronowicz代数的二重中的子代数出现。对于非零的t,Nichols-Woronowicz代数被替换为与经典的杨-巴克斯特方程相关的代数。

英文摘要:

Braided doubles provide a unifying framework for classical and quantum universal enveloping algebras and rational Cherednik algebras. They are a class of algebras with triangular decomposition, arising from a deformation problem, the solutions to which are called quasi-Yetter-Drinfeld modules. A basic family of quasi-YD modules is provided by braidings (matrices satisfying the quantum Yang-Baxter equation); these give rise to quantum versions of the Weyl algebra, where the role of polynomial rings is played by Nichols-Woronowicz algebras. Rational Cherednik algebras for t = 0 emerge as subalgebras in doubles of Nichols-Woronowicz algebras. For nonzero t, the Nichols-Woronowicz algebra is replaced with an algebra associated to the classical Yang-Baxter equation.
