Singular inflation from generalized equation of state fluids
  We study models with a generalized inhomogeneous equation of state fluids, in
the context of singular inflation, focusing to so-called Type IV singular
evolution. In the simplest case, this cosmological fluid is described by an
equation of state with constant $w$, and therefore a direct modification of
this constant $w$ fluid, is achieved by using a generalized form of an equation
of state. We investigate from which models with generalized phenomenological
equation of state, a Type IV singular inflation can be generated and what the
phenomenological implications of this singularity would be. We support our
results with illustrative examples and we also study the impact of the Type IV
singularities on the slow-roll parameters and on the observational inflationary
indices, showing the consistency with Planck mission results. The unification
of singular inflation with singular dark energy era for specific generalized
fluids is also proposed.
