Consequences of field quantization in de sitter type cosmological models

摘要: The present paper may conditionally be divided into three tightly associated parts. first part is a discussion of the necessity conformal covariance general relativistic scalar field equation following from quantum theory. second an objection against assertion or implication in Reps. [3, 5] that De Sitter world (and as consequence, some other cosmological models) rest mass particle cannot zero. In third forbiddenness cubic self-interaction vs. quartic one models under consideration shown. This manifests there exist divergences special type (not ultraviolet) perturbation theory for former interaction, but no such divergence latter. relation results with reality discussed.
