Timelike bounce hypersurfaces in charged null dust collapse
David Bick
We establish results on the dynamics of interacting charged null fluids in general relativity, specifically in the context of the bouncing continuation proposed in [Ori91]. In this…

Caustics in the spherically symmetric Einstein-dust system
David Bick
Caustics-envelopes formed by the trajectories of fluid particles-arise in proposed dynamical extensions for shell-crossing singularities occurring in the Einstein-dust system. In t…
