The Einstein's field equations have been solved by considering time dependent deceleration parameter (DP) which renders the scale factor $a = (t^{n}e^{kt})^{\\frac{1}{m}}$ where $m$, $n$ and $k$ are positive constants. The cosmological term $(\\Lambda(t))$ is found to be positive and a decreasing function of time which supports the result obtained from supernovae Ia observat","authors_text":"Anil Kumar Yadav, A.
