S-brane solutions with (anti-)self-dual parallel charge density form on a Ricci-flat submanifold
H. Dehnen, V. D. Ivashchuk, V. N. Melnikov
A D-dimensional cosmological model with several scalar fields and antisymmetric (p+2)-form is considered. For dimensions D = 4m+1 = 5, 9, 13, ... and p = 2m-1 = 1, 3, 5, ... we obt…
Fluxbrane and S-brane solutions with polynomials related to rank-2 Lie algebras
I. S. Goncharenko, V. D. Ivashchuk, V. N. Melnikov
Composite fluxbrane and S-brane solutions for a wide class of intersection rules are considered. These solutions are defined on a product manifold R_{*} x M_1 x ... x M_n which con…
Non-singular solutions in multidimensional cosmology with a perfect fluid: acceleration and variation of G
V. D. Ivashchuk, S. A. Kononogov, V. N. Melnikov +1
Exact solutions with an exponential behaviour of the scale factors are considered in a multidimensional cosmological model describing the dynamics of n+1 Ricci-flat factor spaces M…
Regular black holes and black universes
K. A. Bronnikov, H. Dehnen, V. N. Melnikov
We give a comparative description of different types of regular static, spherically symmetric black holes (BHs) and discuss in more detail their particular type, which we suggest t…
Multidimensional cosmology with anisotropic fluid: acceleration and variation of G
J. -M. Alimi, V. D. Ivashchuk, S. A. Kononogov +1
A multidimensional cosmological model describing the dynamics of n+1 Ricci-flat factor-spaces M_i in the presence of a one-component anisotropic fluid is considered. The pressures…
Electric S-brane solutions with parallel forms on Ricci-flat factor space
V. D. Ivashchuk, V. N. Melnikov, D. Singleton
In this paper we generalize electric S-brane solutions with maximal number of branes. Previously for the action containing D-dimensional gravity, a scalar field and antisymmetric (…
On the cosmological constant in quantum cosmology
M. I. Kalinin, V. N. Melnikov
Quantization of a dust-like closed isotropic cosmological model with a cosmological constant is realized by the method of B. DeWitt \cite{1}. It is shown that such quantization lea…
Brane world corrections to Newton's law
K. A. Bronnikov, S. A. Kononogov, V. N. Melnikov
We discuss possible variations of the effective gravitational constant with length scale, predicted by most of alternative theories of gravity and unified models of physical intera…
