Scientific paper

We have studied cosmological model generated by perfect fluid coupled with mass less scalar field for Kantowski-Sachs space-time in general theory of relativity. Two different physically viable models of the universe are obtained by using a special law of variation for Hubble’s parameter that yields a constant value of deceleration parameter. Some physical consequences of the models have been discussed in case of Zel’dovich fluid.
