Modified Chaplygin Gas with Variable G and Λ

We consider a modified Chaplygin gas with the gravitational constant G and the cosmological constant 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 formed arbitrarily, and for static universe with constant equation of state, G and Λ should be constant.
