The astronomical observations of the last years show that there are the regions in the Universe with much lower density of matter, than their surroundings. Theoretical studies of the regions (voids) in the model of the expanding Universe are carried

The cosmological model with perfect fluid is considered. We suppose that this model is homogeneous and anisotropic. The analysis of the spatial curvature tensor invariants showed that they have no singularities and depends on arbitrary function ζ(t)

In this work the model of Schwarzschild black hole in the universe filled by dust-like matter is built on the basis of found generalization of Tolman–Bondi solution. A set of possible solutions for this model was analyzed with help of mass function

Stephani cosmological models are considered which describe spacetimes for a shear-free matter distribution and include Friedmann models as a particular case. The possibility is considered of constructing cosmological models in which a change of sign

Different types of T-solutions are investigated. The conditions at which one region of space-time can be described only by a statistic R-solution and another region can be described only by a T-solution are obtained. The common metric for R- and T-so

A model is set up for a homogeneous configuration having the equation of state of a liquid. The equation of motion for the configuration boundary is preserved. It is shown that the spatial curvature can alter during evolution and that the configurati
