摘要

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