Abstract
It is shown that calculation of the anomalous expectation values for t he massless Gross-Neveu model in the Hartree-Fock approximation indica tes the presence of an ordinary chiral phase transition if the couplin g constant has the normal sign (g>0) and of a different transition of the superconductivity type if g<0.
