K-causality and degenerate spacetimes

H. F. Dowker, R. S. Garcia, S. Surya

The causal relation was introduced by Sorkin and Woolgar to extend the standard causal analysis of spacetimes to those that are only . Most of their results also h…

Quantum Radiation from Black Holes and Naked Singularities in Spherical Dust Collapse

T. P. Singh, Cenalo Vaz

A sufficiently massive collapsing star will end its life as a spacetime singularity. The nature of the Hawking radiation emitted during collapse depends critically on whether the s…

Morse index and causal continuity. A criterion for topology change in quantum gravity

H. F. Dowker, R. S. Garcia, S. Surya

Studies in 1+1 dimensions suggest that causally discontinuous topology changing spacetimes are suppressed in quantum gravity. Borde and Sorkin have conjectured that causal disconti…

Spherical gravitational collapse: tangential pressure and related equations of state

Sukratu Barve, T. P. Singh, Louis Witten

We derive an equation for the acceleration of a fluid element in the spherical gravitational collapse of a bounded compact object made up of an imperfect fluid. We show that non-si…

A simple derivation of the naked singularity in spherical dust collapse

Sukratu Barve, T. P. Singh, Cenalo Vaz +1

We describe a simple method of determining whether the singularity that forms in the spherically symmetric collapse of inhomogeneous dust is naked or covered. This derivation consi…

Causal continuity in degenerate spacetimes

A. Borde, H. F. Dowker, R. S. Garcia +2

A change of spatial topology in a causal, compact spacetime cannot occur when the metric is globally Lorentzian. One can however construct a causal metric from a Riemannian metric…
