Qualitative and numerical analysis of the cosmological model based on the asymmetric scalar dublet with minimum connections. IV. Numerical simulations and types of model behavior
Based on the qualitative and numerical analysis of the cosmological model based on an asymmetric scalar doublet of nonlinear minimally interacting scalar fields, classical and phantom, the behavior of the model near hypersurfaces of zero energy is revealed. Numerical models are constructed in which the dynamic system has limit cycles on zero-energy hypersurfaces. Three types of behavior of the cosmological model, which are realized depending on the fundamental constants of scalar fields and initial conditions, are identified. It is shown that in a wide sector of the values of the fundamental constants and initial conditions, cosmological models tend to “stick” to zero-energy hypersurfaces corresponding to 4-dimensional Euclidean space.
