@article{Bhattacharya2011COLLAPSEAD, title={COLLAPSE AND DISPERSAL IN MASSLESS SCALAR FIELD MODELS}, author={Swastik Bhattacharya and Rituparno Goswami and Pankaj S. Joshi}, journal={International Journal of Modern Physics D}, year={2011}, volume={20}, pages={1123-1133} }

The phenomena of collapse and dispersal for a massless scalar field have drawn considerable interest in recent years, mainly from a numerical perspective. We give here a sufficient condition for the dispersal to take place for a scalar field that initially begins with a collapse. It is shown that the change of the gradient of the scalar field from a timelike to a spacelike vector must be accompanied by the dispersal of the scalar field. This result holds independently of any symmetries of the…

Critical Phenomena in Gravitational Collapse

Critical phenomena give a natural route from smooth initial data to arbitrarily large curvatures visible from infinity, and are therefore likely to be relevant for cosmic censorship, quantum gravity, astrophysics, and the general understanding of the dynamics of general relativity.
