Inhomogeneous imperfect fluid inflation
  A generalized equation of state corresponding to a model that includes a
Chaplygin gas and a viscous term is investigated, in the context of the
reconstruction program in scalar field cosmology. The corresponding
inflationary model parameters can be conveniently adjusted in order to
reproduce the most recent PLANCK data. The influence of the Chaplygin gas term
contribution, in relation with previous models, is discussed. Exit from
inflation is shown to occur quite naturally in the new model.
