A method for analytically calculating critical properties of two-dimensional exactly solvable models is presented. It is based on the calculation of finite-size corrections of the critical system and on predictions by conformal field theory. It is applied to the restricted solid-on-solid models...

The finite-size corrections, central charges c and conformal weights Δ of L-state restricted solid-on-solid lattice models and their fusion hierarchies are calculated analytically. This is achieved by solving special functional equations, in the form of inversion identity hierarchies, satisfied...
