Abstract
The cosmological term is achieved with non-static inhomogeneous cosmological models when a perfect fluid generates the gravitational field's source. Einstein's field equations are solved for three physically significant examples (the vacuum cosmological model, the radiating cosmological model, and the Zeldevich model) using the gamma law equation of state.
