A note on the logarithmic (p,p') fusion
arXiv:0710.5157
Abstract
The procedure in [Fuchs et al.] to obtain a fusion algebra from the modular transformation of characters in logarithmic conformal field models is extended to the (p,p') logarithmic models. The resulting fusion algebra coincides with the Grothendieck ring of the quantum group of the (p,p') model.
