The effect of static fluctuations in the phase of the order parameter on thenormal and superconducting properties of a 2D system with attractivefour-fermion interaction has been studied. Analytic expressions for the fermionGreen function, its spectral density and the density of states are derived. Theresultant single-particle Green function clearly demonstrates non-Fermi liquidbehavior. The results show that as the temperature increases through the 2Dcritical temperature the width of the quasiparticle peaks broadenssignificantly. At the same time one retains the gap in quasiparticle spectrum.The spectral density for the dynamical fluctuations can also be obtained.Clearly the dynamical fluctuations fill the gap giving the observed pseudogapbehaviour.Comment: 4 pages, LaTeX; invited paper presented at New^3SC-2, Las Vegas, USA,  199
