Paper detail

Cosmology in two-dimensional dilaton gravity theories

We study some aspects of classical & quantum cosmology in the context of two-dimensionsal dilaton gravity theories with matter being described by a perfect fluid. We derive the classical equations obeyed by the metric function & the dilaton field. An impicit solution for the metric function is obtained & used to discuss possible expansion & contraction scenarios for the universe. Quantization is carried out & finite norm exact solutions of the Wheeler-DeWitt equation are obtained.
