Weak quasitriangular Quasi-Hopf algebra structure of minimal models
Teschner, J. A.
Original · EN
The chiral vertex operators for the minimal models are constructed and used to define a fusion product of representations. The existence of commutativity and associativity operations is proved. The matrix elements of the associativity operations are shown to be given in terms of the 6-j symbols of the weak quasitriangular quasi-Hopf algebra obtained by truncating at roots of unity.
