Abstract

In this paper, we obtained solution of Einstein field equations for Bianchi type VI cosmological model with time dependant cosmological term of the form and . It is observed that cosmological term is decreasing function of time which is consistent with results from recent supernova Ia observations. Also, it is noted that the model approaches to isotropy for = 1. All the physical parameters are calculated and discussed.
