New mathematical framework for spherical gravitational collapse
Roberto Giambo', Fabio Giannoni, Giulio Magli +1
A theorem, giving necessary and sufficient condition for naked singularity formation in spherically symmetric non static spacetimes under hypotheses of physical acceptability, is f…
Naked singularities in dust collapse as an existence problem for O.D.E. at a singular point
Roberto Giambo', Giulio Magli
The final state of the gravitational collapse of a marginally bound dust cloud is formulated in terms of an existence problem for the non-linear differential equation governing rad…
Anisotropic generalizations of de Sitter spacetime
Roberto Giambo'
It is known that de Sitter spacetime can be seen as the solution of field equation for completely isotropic matter. In the present paper a new class of exact solutions in spherical…
New solutions of Einstein equations in spherical symmetry: the Cosmic Censor to the court
Roberto Giambo', Fabio Giannoni, Giulio Magli +1
A new class of solutions of the Einstein field equations in spherical symmetry is found. The new solutions are mathematically described as the metrics admitting separation of varia…
