Scalar field cosmological models with finite scale factor singularities
arXiv:0801.2348 · doi:10.1016/j.physletb.2008.06.077
Abstract
We construct a scalar field based cosmological model, possessing a cosmological singularity characterized by a finite value of the cosmological radius and an infinite scalar curvature. Using the methods of the qualitative theory of differential equations, we give a complete description of the cosmological evolutions in the model under consideration. There are four classes of evolutions, two of which have finite lifetimes, while the other two undergo an infinite expansion.
