Was there a Big Bang?
D. E. Afanasev, M. O. Katanaev
New one parameter family of exact solutions in General Relativity with a scalar field is found. The metric is of Liouville type which admits complete separation of variables in the…
Tube dislocations in gravity
G. de Berredo-Peixoto, M. O. Katanaev
We consider static massive thin cylindrical shells (tubes) as the sources in Einstein's equations. They correspond to $\dl$- and $\dl'$-function type energy-momentum tensors. The c…
Inside the BTZ black hole
G. de Berredo-Peixoto, M. O. Katanaev
We consider static circularly symmetric solution of three-dimensional Einstein's equations with negative cosmological constant (the BTZ black hole). The case of zero cosmological c…
Generalized 2d-dilaton models, the true black hole and quantum integrability
M. O. Katanaev, W. Kummer, H. Liebl +1
All 1+1 dimensional dipheomorphism-invariant models can be viewed in a unified manner. This includes also general dilaton theories and especially spherically symmetric gravity (SSG…
