Accelerated expansion of the universe from the perspective of inhomogeneous cosmology
I. Bormotova, E. Kopteva, M. Churilova +1
We present a special case of the Stephani solution with spherical symmetry while considering different values of spatial curvature. We investigate the dynamics of the universe evol…

Accelerated Expansion of the Universe in the Model with Non-Uniform Pressure
Elena Kopteva, Irina Bormotova, Maria Churilova +1
We present the particular case of the Stephani solution for shear-free perfect fluid with uniform energy density and non-uniform pressure. Such models appeared as possible alternat…

The mass function method for obtaining exact solutions of Einstein equations
Maria Korkina, Elena Kopteva
We show that the mass function method makes it much easier to obtain the exact solutions of Einstein equations. The known solutions for empty space and for the universe filled with…
