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…
Constants of extended Standard Model and search for their temporal variations
S. A. Kononogov, V. N. Melnikov, V. V. Khruschov
Some methods for the determination and the most precise values of constants of an extended Standard Model, which include the gravitation interaction and massive neutrinos, are pres…
Cosmologies from nonlinear multidimensional gravity with acceleration and slowly varying G
K. A. Bronnikov, S. A. Kononogov, V. N. Melnikov +1
We consider multidimensional gravity with a Lagrangian containing the Ricci tensor squared and the Kretschmann invariant. In a Kaluza-Klein approach with a single compact extra spa…
