Abstract
The Cardassian Model for the dark energy, dark matter and unified theory, which have usually invoked as the mostplausible way to explain the recent observational result, have been studied. In this paper we mainly focus our attention
to investigate some observational consequences of a flat, matter dominated and accelerating scenario, on the constraints,
the parameters n and q which fully characterize the Cardassian Model. The dependence of the acceleration red-shift that
is the red-shift at which the Universe begins to accelerate, with the parameters n and q is briefly discussed. When we
consider q = 1 our case 2.1 converges to the case of Cardassian model for the dark energy by S. Sen44. Moreover when
we consider ?r0, the density parameter for radiation, is zero then our case 2.1 converges to the case of Cardassian model
for dark matter by A., Dev20, as a special case.
