Resumen
An effective potential for composite operators is computed at stationary points with different ansatze for the fermion self-energy in abelian and non-abelian theories. The vacuum shows a chiral asymmetric phase with larger stability for a specific ansatz: the one which is harder at high momenta. © 1985.
