Non-minimally Coupled Cosmological Models with the Higgs-like Potentials and Negative Cosmological Constant
I. Ya. Aref'eva, N. V. Bulatov, R. V. Gorbachev +1
We study dynamics of non-minimally coupled scalar field cosmological models with Higgs-like potentials and a negative cosmological constant. In these models the inflationary stage…
FRW Cosmology with Non-positively Defined Higgs Potentials
I. Ya. Aref'eva, N. V. Bulatov, R. V. Gorbachev
We discuss the classical aspects of dynamics of scalar models with non-positive Higgs potentials in the FRW cosmology. These models appear as effective local models in non-local mo…
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…
Null Energy Condition Violation and Classical Stability in the Bianchi I Metric
Irina Ya. Aref'eva, Nikolay V. Bulatov, Liudmila V. Joukovskaya +1
The stability of isotropic cosmological solutions in the Bianchi I model is considered. We prove that the stability of isotropic solutions in the Bianchi I metric for a positive Hu…
