Geodesic motion of test particles in Korkina-Grigoryev metric
Irina Bormotova, Elena Kopteva
We study the geodesic structure of the Korkina-Grigoryev spacetime. The corresponding metric is a generalization of the Schwarzschild geometry to the case involving a massless scal…

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…

The model of the black hole enclosed in dust. The flat space case
Pavlina Jaluvkova, Elena Kopteva, Zdenek Stuchlik
In this work the model is constructed to describe the black hole enclosed in the dust cosmological background in case of zero spatial curvature. This model is based on our exact so…
