Conformal Perturbation Theory

In the last chapters we have obtained numerous results for statistical systems exactly at the critical point. Finite-size corrections were eliminated by the finite-lattice extrapolation procedures described and the finite-size scaling variables were set to zero. We now turn towards an investigation of these and shall show how finite-size corrections and finite-size scaling functions can be derived from the known operator content of a given model. These techniques do not require the integrability of the system under consideration.
