  We analyze non - Fermi liquid (NFL) behavior of fluctuating gap model (FGM)
of pseudogap behavior in both 1D and 2D. We discuss in detail quasiparticle
renormalization (Z - factor), demonstrating a kind of "marginal" Fermi liquid
or Luttinger liquid behavior and topological stability of the "bare" Fermi
surface (Luttinger theorem). In 2D case we discuss effective picture of Fermi
surface "destruction" both in "hot spots" model of dielectric (AFM, CDW)
pseudogap fluctuations, as well as for qualitatively different case of
superconducting d - wave fluctuations, reflecting NFL spectral density behavior
and similar to that observed in ARPES experiments on copper oxides.
