Abstract

In this work, we have considered modified Chaplygin gas with variable G and Λ. The trivial solution describes decelerating phase to accelerating phase of the universe. The non-static with constant equation of state describes the inflationary solution. For static universe, G and Λ must be forms arbitrary and for static universe with constant equation of state G and Λ should be constant.
