Аннотация

Based on the previously formulated mathematical model of a statistical system with scalar interaction of fermions, a cosmological model is studied, based on a one-component statistical system of doubly scalarly charged degenerate fermions interacting with an asymmetric scalar doublet of canonical and phantom scalar fields. A relationship of the presented model with previously studied models based on one-component and two-component fermion systems is investigated. The asymptotic and limiting properties of the cosmological model are investigated, it is shown that among all models there is a class of models with finite lifetime. The asymptotic behavior of models near the corresponding singularities is investigated, a qualitative analysis of the corresponding dynamical system is carried out, and numerical implementations of such models are constructed. Based on numerical integration, it is shown that in the presentmodel there can be transitions froma stable asymptotically vacuum state with a zero canonical field and a constant phantom field, corresponding to the phase of cosmological compression, to a symmetric state corresponding to an expansion phase. The time interval of the transition between these phases is accompanied by oscillations of the canonical scalar field.
