Doubling of background solution in 5D stabilized brane world model
Mikhail N. Smolyakov
We discuss a model providing two different stationary background solutions with flat and metric on the branes under the same values of the fundamental parameters. It is sh…
Stable Exact Solutions in Cosmological Models with Two Scalar Fields
Irina Ya. Aref'eva, Nikolay V. Bulatov, Sergey Yu. Vernov
The stability of isotropic cosmological solutions for two-field models in the Bianchi I metric is considered. We prove that the sufficient conditions for the Lyapunov stability in…
Localization of nonlocal cosmological models with quadratic potentials in the case of double roots
Sergey Yu. Vernov
Nonlocal cosmological models with quadratic potentials are considered. We study the action with an arbitrary analytic function F(\Box_g), which has both double and simple roots. Th…
Cosmological perturbations in SFT inspired non-local scalar field models
Alexey S. Koshelev, Sergey Yu. Vernov
We study cosmological perturbations in models with a single non-local scalar field originating from the string field theory description of the rolling tachyon dynamics. We construc…
