Naked singularities in Tolman-Bondi-de Sitter collapse - art. no. 064017

We study the formation of central naked singularities in spherical dust col lapse with a cosmological constant. We find that the central curvature sing ularity is locally naked, Tipler strong, and generic, in the sense that it forms from a non-zero-measure set of regular initial data. We also find tha t the Weyl and Ricci curvature scalars diverge at the singularity, with the former dominating over the latter, thereby indicating the non-local origin of the singularity.
