Geodesic behaviour around cosmological milestones

Show affiliations


In this paper we provide a thorough classification of Friedman-Lemaître-Robertson-Walker (FLRW) cosmological models in terms of the strong or weak character of their singularities according to the usual definitions. The classification refers to a generalised Puiseux power expansion of the scale factor of the model around a singular event.
