Annotation

A mathematical model of the Universe evolution, based on asymmetric doublet of classical and phantom dcalar Higgs fields with a kinetic connection between the components, has been constructed and studied. A detailed qualitative analysis was carried out, the properties of the model's symmetry and invarience with respect to the similariry transformations of fundamental constants were proven. The principles of numerical modeling are formulated and an example of numerical modeling of the evolution of the model for a specific set of fundamental constants and initial conditions is given. the asymptotic behavior of the model near cosmological singularities is studied. It is shown that cosmological model near singularities manifests itself as an ideal fluid with an extremelly ripid equation of state. Keywords: cosmological model, phantom and classical scalar fields, kinetic interection, quality analysis, asymptotic behavior, numerrical modeling.
