Abstract: (Springer)

In our present work, we study the dynamics of the universe by using an interacting quintessence model, where equation of state parameter of dark energy varies between −1 and 0. First we calculated the dark energy density parameter and using that we have picturised the evolution of the deceleration parameter. From our analysis, we found that present universe is undergoing an accelerated phase of expansion where as the early time expansion was decelerated one. Our result also predicts that the transition from deceleration to acceleration would be occurred at

0.189t_0

where

t_0

is the present age of the universe.
