Variations of constants as a test of gravity, cosmology and unified models
V. N. Melnikov
Gravitation as a fundamental interaction that governs all phenomena at large and very small scales, but still not well understood at a quantum level, is a cardinal missing link in…
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…
Composite electric S-brane solutions with maximal number of branes and several scalar fields
H. Dehnen, V. D. Ivashchuk, V. N. Melnikov
A (n+1)-dimensional cosmological model with a set of scalar fields and antisymmetric (p+2)-form is considered. Some of scalar fields may have negative kinetic terms, i.e. they may…
Composite electric S-brane solutions with maximal number of branes
V. D. Ivashchuk, D. Singleton
In this paper we consider (n+1)-dimensional cosmological model with scalar field and antisymmetric (p+2)-form. Using an electric composite Sp-brane ansatz the field equations for t…
Exact solutions in multidimensional gravity with antisymmetric forms
V. D. Ivashchuk, V. N. Melnikov
This topical review deals with a multidimensional gravitational model containing dilatonic scalar fields and antisymmetric forms. The manifold is chosen in the form M = M_0 x M_1 x…
Post-Newtonian parameters for general black hole and spherically symmetric p-brane solutions
V. D. Ivashchuk, V. S. Manko, V. N. Melnikov
Black hole p-brane solutions for a wide class of intersection rules are considered. The solutions are defined on a manifold which contains a product of n-1 Ricci-flat "internal'' s…
On quantum analogues of p-brane black holes
V. D. Ivashchuk, M. Kenmoku, V. N. Melnikov
In a multidimensional model with several scalar fields and an m-form we deal with classical spherically symmetric solutions with one (electric or magnetic) p-brane and Ricci-flat i…
P-brane black holes for general intersections
V. D. Ivashchuk, V. N. Melnikov
Black hole generalized p-brane solutions for a wide class of intersection rules are presented. The solutions are defined on a manifold that contains a product of n - 1 Ricci-flat i…
Hyperbolic Kac-Moody Algebra from Intersecting p-branes
V. D. Ivashchuk, S. -W. Kim, V. N. Melnikov
A subclass of recently discovered class of solutions in multidimensional gravity with intersecting p-branes related to Lie algebras and governed by a set of harmonic functions is c…
Multidimensional sigma-models with composite electric p-branes
V. D. Ivashchuk, V. N. Melnikov, M. Rainer
We consider a gravitational model on a manifold M = M_0 x M_1 x...x M_n with oriented connected Einstein internal spaces M_1,...,M_n. The matter part of the action contains several…
