Description
Quantum cosmology is often analyzed in a model-dependent way, following specific quantization schemes. This talk instead focuses on general properties and related questions implied by the common separation of modes into an expanding background and evolving perturbations. While this separation is well-understood classically, it gives rise to important questions about Casimir energies, covariance, and modified dynamics on the quantum level.
