Abstract
We have studied flat FRW cosmological model of the universe filled with an ideal fluid with quadratic equation of state (EOS) with time dependent parameters \(\omega(t)\) and \(\varLambda(t)\). We found the equation of the state parameter \(\omega(t)\) is less than −1 and also found Little Rip (LR) and Pseudo Rip (PR) behavior for dark energy.
