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…
On avoiding cosmological oscillating behavior for S-brane solutions with diagonal metrics
V. D. Ivashchuk, V. N. Melnikov, D. Singleton
In certain string inspired higher dimensional cosmological models it has been conjectured that there is generic, chaotic oscillating behavior near the initial singularity -- the Ka…
Composite Electric -Brane Solutions with Maximal Charge Densities
V. D. Ivashchuk, D. Singleton
In this paper we consider -dimensional cosmological model with scalar field and antisymmetric -form. Using an electric composite -brane ansatz the field equations…
Dually-charged mesoatom on the space of constant negative curvature
V. D. Ivashchuk, V. N. Melnikov
The discrete spectrum solutions corresponding to dually-charged mesoatom on the space of constant negative curvature are obtained. The discrete spectrum of energies is finite and v…
Non-singular solutions in multidimensional model with scalar fields and exponential potential
J. -M. Alimi, V. D. Ivashchuk, V. N. Melnikov
Using developed earlier our methods for multidimensional models \cite{M1,M2,M3} a family of cosmological-type solutions in D-dimensional model with two sets of scalar fields \vecϕ…
