A Note on Genericity and Stability of Black Holes and Naked Singularities in Dust Collapse
Ravindra V. Saraykar, Pankaj S. Joshi
We comment here on the results in Ref [4] that showed naked singularities in dynamical gravitational collapse of inhomogeneous dust to be stable but non-generic. The definition of…

Trapped surfaces and horizons in static massless scalar field spacetimes
Swastik Bhattacharya, Pankaj S. Joshi
We consider here the existence and structure of trapped surfaces, horizons and singularities in spherically symmetric static massless scalar field spacetimes. Earlier studies have…

Regularity of initial data in dynamical massless scalar field models
Swastik Bhattacharya, Pankaj S. Joshi
We discuss here the issue of regularity of initial data for dynamical spherically symmetric massless scalar field models in a spacetime. Generalizing the known solutions of Einstei…
