- Аннотация: The stability of isotropic cosmological solutions for two-field models in the Bianchi I metrics is considered. We have proved that the sufficient conditions for Lyapunov stability in the Friedmann-Robertson-Walker metric are sufficient for the stability under anisotropic perturbations in the Bianchi I metric as well. The standard way to construct cosmological models with exact solutions in the Friedmann-Robertson-Walker metric is the superpotential method. We have used the superpotential method to construct stable kink-type solutions and obtained conditions on superpotential, which are sufficient conditions for the Lyapunov stability. We analyze the stability of isotropic kink-type solutions for quintom models related to the string field theory.
