Abstract

The dynamics of a radiating perfect fluid universe coupled with scalar field and heat flux are studied in the nonstatic Godel-type universe including the cosmological constant and obtained some exact solutions of Einstein field equations. The solutions have nonzero expansion, shear, and rotating universe. Various physical and geometrical properties of the model are also discussed and the temperature distribution is also given explicitly.
