Cosmological Models with Rotation

A stationary cosmological model with rotation is constructed for the Ozsvath–Schucking metric where perfect fluid which is not comoving with the system is a source of the gravitational field. A nonstationary cosmological model for the Bianchi metric of type IX is also developed. This is characterized by expansion, rotation and acceleration. A co-moving with the system anisotropic liquid is a source of the gravitational field in this model.
