Annotation
The Gross-Neveu model with violated Lorentz invariance is analyzed. The effective potential for the 3D and 2D cases is calculated. The gap equation is obtained and the symmetry features of the model are considered. Dimensional reduction allows the establishment of the concordance between the results for a different number of measurements.
