The generalized Lemaitre-Tolman-Bondi solutions with nonzero pressure in modeling the cosmological black holes
E. Kopteva, P. Jaluvkova, Z. Stuchlik
In this work we have obtained the set of new exact solutions of the Einstein equations that generalize the known Lemaitre-Tolman-Bondi solution for the certain case of nonzero pres…

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…
