On the oscillation-driven cosmological expansion at the post-inflation stage
arXiv:1611.03734 · doi:10.1134/S0202289317010078
Abstract
Dynamics of the inflaton scalar field oscillating around a minimum of the singular potentials in the expanding Universe is investigated. Asymptotic formulas are obtained describing the cosmological expansion at the late times. The problem of stability of the oscillations considered and the related phenomenon of the field fragmentation are briefly discussed.
