Qualitative analysis of collapsing isotropic fluid spacetimes
Roberto Giambò, Giulio Magli
The structure of the Einstein field equations describing the gravitational collapse of spherically symmetric isotropic fluids is analyzed here for general equations of state. A sui…
Dynamics And Thermodynamics Of Blackholes And Naked Singularities II
Lorenzo Fatibene, Mauro Francaviglia, Roberto Giambò +1
Proceedings of the second edition of the international Workshop "Dynamics and Thermodynamics of Blackholes and Naked Singularities" (Department of Mathematics of the Politecnico of…
Genericity of blackhole formation in the gravitational collapse of homogeneous self-interacting scalar fields
R. Giambó, F. Giannoni, G. Magli
The gravitational collapse of a wide class of self-interacting homogeneous scalar fields models is analyzed. The class is characterized by certain general conditions on the scalar…
The dynamical behaviour of homogeneous scalar-field spacetimes with general self-interaction potentials
Roberto Giambó, Fabio Giannoni, Giulio Magli
The dynamics of homogeneous Robertson--Walker cosmological models with a self-interacting scalar field source is examined here in full generality, requiring only the scalar field p…
A variational approach to homogeneous scalar fields in General Relativity
R. Giambo', F. Giannoni, G. Magli
A result of existence of homogeneous scalar field solutions between prescribed configurations is given, using a modified version of Euler--Maupertuis least action variational princ…
Dynamics and Thermodynamics of Blackholes and Naked Singularities
Lorenzo Fatibene, Mauro Francaviglia, Roberto Giambo' +1
Proceedings of the international Workshop on ``Dynamics and Thermodynamics of Blackholes and Naked Singularities``, that took place at the Department of Mathematics of the Politecn…
