关于双参数量子群的注记(I)
Notes on two-parameter quantum groups, (I)
摘要:
利用欧拉形式给出了一类与半单李代数相关的双参数量子群的一个较简单的定义.在一定条件下,它们的正部分是彼此的2-上循环变形。给出了正部分的算子实现。
英文摘要:
A simpler definition for a class of two-parameter quantum groups associated to semisimple Lie algebras is given in terms of Euler form. Their positive parts turn out to be 2-cocycle deformations of each other under some conditions. An operator realization of the positive part is given.
