    Role of Modified Chaplygin Gas in Accelerated Universe
    (2011-07-06) Debnath, Ujjal; Banerjee, A.; Chakraborty, Subenoy
    In this paper we have considered a model of modified Chaplygin gas and its role in accelerating phase of the universe. We have assumed that the equation of state of this modified model is valid from the radiation era to ΛCDM model. We have used recently developed statefinder parameters in characterizing different phase of the universe diagrammatically.
