Abstract
A class of explicit and exact solutions is obtained for the equations gover ning the evolution of spatially flat FLRW spacetimes in interaction with a classical massive scalar field in the presence of conformal coupling and of a quartic self-interaction potential. These solutions only exist for nonva nishing cosmological constant. The equation of state is calculated self-con sistently.
