On physical foundations and observational effects of cosmic rotation

Abstract

An overview of the cosmological models with expansion, shear and rotation is presented. Problems of the rotating models are discussed, their general kinematic properties and dynamical realizations are described. A particular attention is paid to the discussion of possible observational effects which could be used to estimate or to put limits on the cosmic rotation.
