U_q(sl(2,R))的模二重的R-算子、余积和Haar-测度

R-operator, co-product and Haar-measure for the modular double of U_q(sl(2,R))

A. Bytsko, J. Teschner

摘要:

U_q(sl(2,R))的某类酉表示具有这样的性质:对于特定的波浪号{q}(q),它是U_{波浪号{q}}(sl(2,R))的一种表示。Faddeev曾提出把量子群U_q(sl(2,R))和U_{tilde{q}}(sl(2,R))统一到某个扩大的对象中,为此他创造了“模双”的名称。本文研究了U_q(sl(2,R))的模二重的R-算子、余积和Haar-测度,并建立了它们的主要性质。特别地,证明了[PT 2]中构造的Clebsch-Gordan映射对角化了这个R-算子.

英文摘要:

A certain class of unitary representations of U_q(sl(2,R)) has the property of being simultanenously a representation of U_{tilde{q}}(sl(2,R)) for a particular choice of tilde{q}(q). Faddeev has proposed to unify the quantum groups U_q(sl(2,R)) and U_{tilde{q}}(sl(2,R)) into some enlarged object for which he has coined the name ``modular double''. We study the R-operator, the co-product and the Haar-measure for the modular double of U_q(sl(2,R)) and establish their main properties. In particular it is shown that the Clebsch-Gordan maps constructed in [PT2] diagonalize this R-operator.
