Description
Cosmological models of our universe are based on relations between the scale factor, the Hubble parameter and the matter density determined by general relativity combined with simplified matter models. We investigate the quantum analogue of these relations by implementing the results for expectation values of the operators representing the quantum counterparts of the cosmological parameters for perfect fluid quantum cosmological models derived from the canonical quantization of unimodular gravity which is equivalent to general relativity on the classical level. We further discuss the role of quantum uncertainties evolving in time for quantum deviations in general and causality in particular.
