Will there be again a transition from acceleration to deceleration in course of the dark energy evolution of the universe?

Understand

In this work we consider the evolution of the interactive dark fluids in the background of homogeneous and isotropic FRW model of the universe.

• The dark fluids consist of a warm dark matter and a dark energy and both are described as perfect fluid with barotropic equation of state.
• The dark species interact non-gravitationally through an additional term in the energy conservation equations.
• An autonomous system is formed in the energy density spaces and fixed points are analyzed.
