Dilaton gravity, (quasi-) black holes, and scalar charge
K. A. Bronnikov, J. C. Fabris, R. Silveira +1
We consider static electrically charged dust configurations in the framework of Einstein-Maxwell-dilaton gravity with the interaction term P(χ) F_{mn} F^{mn} in the Lagrangian, whe…
New exact cosmologies on the brane
Artyom V. Astashenok, Artyom V. Yurov, Sergey V. Chervon +2
We develop a method for constructing exact cosmological solutions in brane world cosmology. New classes of cosmological solutions on Randall-Sandrum brane are obtained. The superpo…
Further stable neutron star models from f(R) gravity
Artyom V. Astashenok, Salvatore Capozziello, Sergei D. Odintsov
Neutron star models in perturbative gravity are considered with realistic equations of state. In particular, we consider the FPS, SLy and other equations of state and a case…
The possible resolution of Boltzmann brains problem in phantom cosmology
Artyom V. Astashenok, Artyom V. Yurov, Valerian V. Yurov
We consider the well-known Boltzmann brains problem in frames of simple phantom energy models with little rip and big rip singularity. It is showed that these models (i) satisfy to…
Effective Dark Energy Models and Dark Energy Models with Bounce in frames of Gravity
Artyom V. Astashenok
Various cosmological models in frames of gravity are considered. The general scheme of constructing effective dark energy models with various evolution is presented. It is s…
Collision of water wave solitons
N. Fenyvesi, G. Bene
A classification of the time evolution of the two-soliton solutions of the Boussinesq equation is given, based on the number of extrema of the wave. For solitons moving in the same…
