摘要
In this paper, we have considered a model of modified Chaplygin gas and its role in the accelerating phase of the universe. We have assumed that the equation of state of this modified model is valid from the radiation era to the ACDM model. We have used recently developed statefinder parameters in characterizing different phases of the universe diagrammatically.
