Abstract
We compute the corrections of next to leading order in the expansion to the effective potential of a system described by a Ginzburg-Landau model with components and quartic interaction, in the case of spontaneous symmetry breaking. The method we apply allows to generalize in a simple way the so-called Self-Consistent Screened Approximation (SCSA).
