Flat Solution

We present a Petrov type II general space–time which violates causality in the sense that it allows for the formation of closed timelike curves that appear after a definite instant of time. The metric, which is axially symmetric, admits an expansion-free, twist-free and shear-free null geodesic congruence. From the general metric, we obtain two particular type II metrics. One is a vacuum solution while the other represents a Ricci flat solution with a negative cosmological constant.

Relativistic Matter

A Bianchi type II cosmological model with expansion and rotation has been constructed. The model describes the Friedmannian stage of the Universe’s evolution including a subsequent transition to the accelerated exponential expansion observed nowadays. The gravitational field sources of the model are an ultra-relativistic matter, dust and co-moving anisotropic rotating dark energy. The possibility of detecting the cosmological rotation by astrophysical observations is discussed.

The Mean

“Dynamical mixing”, i.e. relaxation of a stellar phase space distribution through interaction with the mean gravitational field, is numerically investigated for a one-dimensional self-gravitating stellar gas. Qualitative results are presented in the form of a motion picture of the flow of phase points (representing homogeneous slabs of stars) in two-dimensional phase space.
