| Abstract: | The equation of state is discussed for a system of degenerate fermions. The formation of bound states is allowed for; the latter may exhibit the Bose-Einstein condensation. A complex representation is given which includes bound and scattering two-particle states as well. Different (generalized) representations in terms of scattering quantities are given for the continuum contribution. |
