Scalar field cosmological models with finite scale factor singularities

Understand

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.
