Bibliographic description in the original language

Yu. G. Ignat'ev and A. A. Agathonov. Dynamics of cosmological models with nonlinear classical and phantom scalar fields. II. Qualitative analysis and numerical modeling // Russian Physics Journal, Vol. 61, No. 11, 2019, pp. 2092-2104

Annotation

Mathematical models describing the cosmological evolution of classical and phantom scalar fields with self-action are formulated and analyzed. Systems of dynamical equations in the plane, describing homogeneous cosmological models, have been obtained. It is shown that depending on the parameters of the field model, it is possible to violate the singly-connectedness of the phase space of the corresponding dynamical model.

Keywords

cosmological model, qualitative analysis, phantom scalar field.
