Rotating Melvin-like universes and wormholes in general relativity
K. A. Bronnikov, V. G. Krechet, V. B. Oshurko
We find a family of exact solutions to the Einstein-Maxwell equations for rotating cylindrically symmetric distributions of a perfect fluid with the equation of state ($|w…

Potentially observable cylindrical wormholes without exotic matter in general relativity
K. A. Bronnikov, V. G. Krechet
All known solutions to the Einstein equations describing rotating cylindrical wormholes lack asymptotic flatness and therefore cannot describe wormhole entrances as local objects i…

Time-dependent Spherically-symmetric 5-D Vacuum Solutions
Sergey S. Kokarev, Vladimir G. Krechet
Vacuum 5-D Einstein equations with spherical symmetry and t-dependence are considered. For the case of separating variables several classes of exact solutions are obtained. Effecti…
