An effective functional for strongly correlated systems is obtained by means of generalized coherent states with respect to the supergroup. The existence of anomalous symmetries in the complete range of coupling constants of the interelectron interaction is demonstrated. A scheme of breaking of these symmetries is proposed. The behavior of the effective mass is studied.
