摘要

We present a new form of the well-known Chaplygin gas model by introducing inhomogeneity in the equation of state. This model explains omega = -1 crossing. We also give a graphic representation of the model using the {r, s} parameters. We considered an interaction of this model with a scalar field by introducing a phenomenological coupling function and show that the potential decays with time.
