Canonical wave packets in quantum cosmology.

We discuss the construction of wave packets resulting from solutions of a class of Wheeler-DeWitt equations in Robertson-Walker-type cosmologies, for arbitrary curvature. We show that there always exists a 'canonical initial slope' for a given initial wavefunction, which optimizes some desirable properties of the resulting wave packet, most importantly a good classical-quantum correspondence. This can be properly denoted as a canonical wave packet. We introduce a general method for finding these canonical initial slopes which is a generalization of our earlier work. [ABSTRACT FROM AUTHOR]
