General solutions for flat Friedmann universe filled by perfect fluid and scalar field with exponential potential
H. Dehnen, V. R. Gavrilov, V. N. Melnikov
We study integrability by quadrature of a spatially flat Friedmann model containing both a minimally coupled scalar field with an exponential potential $V(ϕ)\sim\exp[-\sqrt{6}σ…
Simulation of intersecting black brane solutions
V. D. Ivashchuk, V. N. Melnikov, A. B. Selivanov
A family of spherically symmetric solutions with horizon in the model with multi-component anisotropic fluid (MCAF) is obtained. The metric of any solution contains n-1 Ricci-flat…
On black hole solutions in model with anisotropic fluid
H. Dehnen, V. D. Ivashchuk, V. N. Melnikov
A family of spherically symmetric solutions in the model with 1-component anisotropic fluid is considered. The metric of the solution depends on a parameter q > 0 relating radial p…
Possible time variations of G in scalar-tensor theories of gravity
K. A. Bronnikov, V. N. Melnikov, Mario Novello
We estimate the possible variations of the gravitational constant G in the framework of a generalized (Bergmann-Wagoner-Nordtvedt) scalar-tensor theory of gravity on the basis of t…
Black-brane solution for A_3 algebra
M. A. Grebeniuk, V. D. Ivashchuk, V. N. Melnikov
Black p-brane solutions for a wide class of intersection rules and Ricci-flat ``internal'' spaces are considered. They are defined up to moduli functions H_s obeying non-linear dif…
Problems of G and multidimensional models
V. N. Melnikov, V. D. Ivashchuk
The relations for G-dot in multidimensional model with Ricci-flat internal space and multicomponent perfect fluid are obtained. A two-component example: dust + 5-brane, is consider…
Multidimensional Black Hole Solutions In Model With Perfect Fluid
V. D. Ivashchuk, V. N. Melnikov, A. B. Selivanov
A family of black-hole solutions in the model with 1-component perfect fluid is obtained. The metric of any solution contains (n -1) Ricci-flat "internal space" metrics and for cer…
