Time and Evolution in Quantum and Classical Cosmology

Time and Evolution in Quantum and Classical Cosmology

We analyze the issue of dynamical evolution and time in quantum cosmology. We emphasize the problem of choice of phase space variables that can play the role of a time parameter in such a way that for expectation values of quantum operators the classical evolution is reproduced. We show that it is n...
