Query: Role Of Generalized Cosmic Chaplygin Gas In Accelerating Universe : A
  Field Theoretical Prescription   In this paper we investigate the role played by dark energy in the form of
Generalized cosmic Chaplygin gas in an accelerating universe described by FRW
cosmology. We have tried to describe the model from the theoretical point of
view of a field, by introducing a scalar field $\phi$ and a self interacting
potential $V(\phi)$. The corresponding expressions for the field are obtained
for the given model. Statefinder parameters have been used to characterize the
dark energy model. Plots have been generated for characterizing different
phases of universe diagrammatically and a comparative study is performed with
the Modified Chaplygin gas model. As an outcome of the study, Generalized
cosmic Chaplygin gas is identified as a much less constrained form of dark
energy as compared to modified Chaplygin gas.
