| contents | We have explored the possibility of the co-existence of two forms of dark energy in the form of an alternative Generalized Chaplygin Gas (GCG) along with a scalar field of field theoretic or extra dimensional origin in the background of a fractal universe. The essential physical model parameters have been computed and their variations have been plotted. Fractal cosmology in an universe dominated by the alternative GCG (overcoming the drawbacks of the conventional form of GCG) has also been studied by computing the equation of state, deceleration and statefinder parameters. Their variations with the redshift have also been studied. We have tried to construct alternative cosmological models deviating from standard cosmology that can be put to observational testing. |
