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…
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 (…
Electric S-brane solutions with a parallel charge density form on a Ricci-flat factor space
I. S. Goncharenko, V. D. Ivashchuk, S. Rudametkin-Aguilar +1
We generalize the previously studied cosmological solutions in D-dimensional gravity with an antisymmetric (p+2)-form to the case when the spatial part of the metric is Ricci-flat…
On time variation of G in multidimensional models with two curvatures
H. Dehnen, V. D. Ivashchuk, S. A. Kononogov +1
Expressions for G-dot are considered in a multidimensional model with an Einstein internal space and a multicomponent perfect fluid. In the case of two non-zero curvatures without…
