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…
