Two-Fluid Scenario for Dark Energy Cosmological Model in Five Dimensional Kaluza-Klein Space Time

In this work, we investigate the evolution of the dark energy equation of state parameter in a five-dimensional Kaluza-Klein homogeneous and isotropic cosmological model filled with a barotropic fluid and a dark fluid. We adopt a special form of the deceleration parameter, q = - (aä/(à2)) = -1 + α/(...
