QUANTUM POTENTIAL AND COSMOLOGICAL SINGULARITIES

We apply the de Broglie-Bohm interpretation to the Wheeler-DeWitt equa tion for the quantum FRW cosmological model with a minimal massless sc alar field. We find that the quantum FRW cosmological model has quantu m potential dominated solutions that avoid the initial and the final c osmological singularities. It is suggested that the quantum potential and the back-reaction of geometry and matter fields may change the pro perty of the cosmological singularities of the universe.
