Bianchi Type VIII Cosmological Models with Rotating Dark Energy

摘要

In the framework of general relativity, we have built nonstationary Bianchi type VIII cosmological models with rotation. The sources of gravity are, in the first case, a comoving perfect fluid along with non-comoving dust, in another case, a comoving perfect fluid and pure radiation, and in the third case, a comoving anisotropic fluid. All models contain a rotating dark energy.
