Notes on Two-Parameter Quantum Groups, (II)

This article is the sequel to 11 Hu , N. , Pei , Y. ( 2008 ). Notes on two-parameter quantum groups, (I) . Sci. in China, Ser. A 51 ( 6 ): 1101 – 1110 . Google Scholar]] to study the deformed structures and representations of two-parameter quantum groups U _{r, s} (𝔤) associated to the finite dimensional simple Lie algebras 𝔤. An equivalence of the braided tensor categories 𝒪 ^{r, s} and 𝒪 ^q under the assumption rs ^?1 = q ² is explicitly established.
