The exact renormalisation group equation and the perturbed unitary minimal models
arXiv:hep-th/0008233 · doi:10.1088/1126-6708/2000/07/053
Abstract
The exact renormalisation group equation is studied for a two-dimensional theory with exponential interaction and a background charge at infinity. The motivation for studying this interaction is the flow between unitary minimal models perturbed by Phi_{(1,3)}, and their realisation in terms of a quantum group restricted sine-Gordon model.
