AbstractA proof of critical conformal invariance of Green’s functions for a quite wide class of models possessing critical scale invariance is given. A simple method for establishing critical conformal invariance of a composite operator, which has a certain critical dimension, is also presented. The method is illustrated with the example of the Gross--Neveu model and the exponents et at order $1/n^3$, Dl and $1/ u$ at order $1/n^2$ are calculated with the conformal bootstrap method.
