| contents | Cosmological models based on an asymmetric scalar Higgs doublet (canonical $Φ$ and phantom $ϕ$ fields) with potential interaction between the components are proposed. A qualitative analysis of the corresponding dynamic systems is performed and their transformation properties with respect to similarity transformations of fundamental constants are revealed. Asymptotic behavior of this class of cosmological models near cosmological singularities is investigated. Numerical simulations revealed a number of interesting features of these models, in particular, the possibility of a fairly long ``waiting phase'', during which the Universe is almost Euclidean, as well as the presence of bounce points, in the vicinity of which strong oscillations of scalar potentials occur. Keywords: Asymmetric scalar Higgs doublet, cosmological models, qualitative analysis, asymptotic behavior, waiting phase, bounces. |
