In this work, we have considered $N (=4+d)$-dimensional Einstein field equations in which 4-dimensional space-time which is described by a FRW metric and that of the extra $d$-dimensions by an Euclide...
A dark energy model alternative to generalized Chaplygin gas

2010/12/27
We propose a new fluid model of dark energy for $-1 \leq \omega_{\text{eff}} \leq 0$ as an alternative to the generalized Chaplygin gas models. The energy density of dark energy fluid is severely supp...

In this paper, the holographic dark energy model with new infrared cut-off proposed by Granda
and Oliveros has been investigated in spatially non flat universe.

This letter discusses a modified Friedmann-Robertson-Walker cosmology in which the equation of state behaves like p = 3hamrn r; (h;m;n) 2 R. Many interesting features are revealed in particu...
