A new class of normal Fermi liquids
Volovik G. E.
The topological structure of the Green's function of the Fermi liquid is analyzed. This structure does not change upon transition to a marginal Fermi liquid or a Luttinger Fermi liquid. It changes, however, upon transition to a state such as the fermion condensate, in which the Fermi surface spreads into a Fermi band.
