Yu. G. Ignat'ev, A. R. Samigullina. On euclidean limit cycles in cosmological models based on scalar fields // Russian Physics Journal, Vol. 62, No. 4, P. 618-626

Annotation

A detailed analysis of the phase trajectories of cosmological models based on classical and scalar fields near surfaces of zero effective energy has been carried out. A study of the differential parameters of the convergence of phase trajectories to a zero-energy surface boundary shows that the phase trajectories merge within a finite time with the phase trajectories of free oscillations corresponding to zero effective energy. This confirms the assumption formulated in a number of previous works by one of the authors about the existence of Euclidean limit cycles in cosmological models based on scalar fields with a Higgs interaction potential.
