    • Abstract


      Ricci dark energy (RDE) model in the framework of bouncing Universe is considered. Both the interacting and the non-interacting cases of the Ricci model of dark energy have been studied. Expressions for important cosmic parameters are reconstructed for the assumed model. It is noticed that the Universe undergoes a continuous expansion with a negative deceleration parameter for two scenarios. Also, Om diagnostic parameter has been established showing a type of quintessence-like behaviour over the given time range. The total entropy of the system is calculated and the validity of the generalised second law of thermodynamics is studied.
