Canonical Quantization and Expanding Metrics
arXiv:gr-qc/9807002 · doi:10.1016/S0375-9601(98)00913-X
Abstract
The canonical formalism for expanding metrics scenarios is presented. Non-unitary time evolution implied by expanding geometry is described as a trajectory over unitarily inequivalent representations at different times of the canonical commutation relations. Thermal properties of inflating Universe are also discussed.
