FEATURES OF PHASE TRAJECTORIES IN THE COMPLETE MODEL OF COSMOLOGICAL EVOLUTION BASED ON CLASSICAL SCALAR FIELD WITH HIGGS POTENTIAL
Samigullina A.R.
A study and computer simulation of the complete model of the cosmological evolution of the classical scalar field with the Higgs potential is carried out without the assumption of the non-negativity of the Hubble constant. It is shown that in most cases of initial conditions the cosmological model passes from the expansion stage to the contraction stage. Thus, cosmological models based on the classical Higgs field are unstable with respect to finite perturbations.
Keywords: cosmological models, Higgs fields, Einstein-Higgs hypersurface, global behavior.
