Abstract

We have studied various classical solutions in cosmology. In particular, we have obtained general classical solutions in pure cosmology. Even in the quantum theory, we can solve the Wheeler - DeWitt equation in pure cosmology exactly. We have studied the problem of time by investigating the correspondence between these classical and quantum solutions in cosmology.
