Some Classes of Interacting Two-Fluid Model of the Expanding Universe

Subhra Bhattacharya

We consider interacting dark matter-dark energy models arising out of a general interaction term $Q=f(\ddot{I}{}_m,\ddot{I}{}_d,\dot{\ddot{I}}{}_m,\dot{\ddot{I}}{}_d).$ Here $f$ is a functional relation conne…
