1302.5400 (S. E. Derkachov et al.)

3j-symbol for the modular double of SL_q(2,R) revisited    [PDF]

S. E. Derkachov, L. D. Faddeev
Modular double of quantum group SL_q(2,R) with |q|=1 has a series of selfadjoint irreducible representations parameterized by s. Ponsot and Teschner considered a decomposition of the tensor product of two representations into irreducibles. In our paper we give more detailed derivation and some new proofs.
