Irreversibility of the Flux of the Renormalization Group in a 2D Field Theory

Eduardo Velasco will present the paper "Irreversibility of the Flux of the Renormalization Group in a 2D Field Theory" por A.B. Zamolodchikov (JETP Lett. 43 (1986) 730-732, Pisma Zh.Eksp.Teor.Fiz. 43 (1986) 565-567). El abstract es el siguiente:

"There exists a function c(g) of the coupling constant g in a 2D renormalizable field theory which decreases monotonically under the influence of a renormalization group transformation. This function has constant values only at fixed points, where c is the same as the central charge of a Virasoro algebra of the corresponding conformal field theory."
