Cyclic universe with an inflationary phase from a cosmological model with real gas quintessence

Research output: Contribution to journalArticlepeer-review

Abstract

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.
