- Title
BAROTROPIC FRW COSMOLOGIES WITH A DIRAC-LIKE PARAMETER.

- Abstract
Using the known connection between Schrödinger-like equations and Dirac-like equations in the supersymmetric context, we discuss an extension of FRW barotropic cosmologies in which a Dirac mass-like parameter is introduced. New Hubble cosmological parameters HK(η) depending on the Dirac-like parameter are plotted and compared with the standard Hubble case H0(η). The new HK(η) are complex quantities. The imaginary part is a supersymmetric way of introducing dissipation and instabilities in the barotropic FRW hydrodynamics.
