In the framework of the Sine-Gordon (SG) theory we will present the construction of a dynamical Virasoro symmetry which has nothing to do with the space-time Virasoro symmetry of 2D CFT. Although, it is non-local in the SG field theory, nevertheless it gives rise to a local action on specific N-soliton solution variables. These {\it analytic} variables possess a beautiful geometrical meaning and enter the Form Factor expressions. At the end, we will also give some preliminary hints about the…

Universal amplitude ratios of the renormalization group: two-dimensional tricritical Ising model.

The universal amplitude ratios for the tricritical Ising model in two dimensions are computed by using several theoretical methods from perturbed conformal field theory and scattering integrable quantum field theory, and results coming from a numerical determination of the energy eigenvalues and eigenvectors of off-critical systems in an infinite cylinder.
