Electric S-brane solutions corresponding to rank-2 Lie algebras: acceleration and small variation of G
V. D. Ivashchuk, S. A. Kononogov, V. N. Melnikov
Electric S-brane solutions with two non-composite electric branes and a set of l scalar fields are considered. The intersection rules for branes correspond to Lie algebras A_2, C_2…
On billiard approach in multidimensional cosmological models
V. D. Ivashchuk, V. N. Melnikov
A short overview of the billiard approach for cosmological-type models with n Einstein factor-spaces is presented. We start with the billiard representation for pseudo-Euclidean To…
Billiard representation for pseudo-Euclidean Toda-like systems of cosmological origin
V. D. Ivashchuk, V. N. Melnikov
The pseudo-Euclidean Toda-like system of cosmological origin is considered. When certain restrictions on the parameters of the model are imposed, the dynamics of the model near the…
On calculation of fluxbrane polynomials corresponding to classical series of Lie algebras
A. A. Golubtsova, V. D. Ivashchuk
We present a description of computational program (written in Maple) for calculation of fluxbrane polynomials corresponding to classical simple Lie algebras. These polynomials defi…
