Cyclic Universe with an Inflationary Phase from a Cosmological Model
  with Real Gas Quintessence
  Phase-plane stability analysis of a dynamical system describing the Universe
as a two-fraction fluid containing baryonic dust and real virial gas
quintessence is presented. Existence of a stable periodic solution experiencing
inflationary periods is shown. A van der Waals quintessence model is revisited
and cyclic Universe solution again found.
