Absence of singularities in a cosmological perfect fluid solution
F. J. Chinea, L. Fernández-Jambrina, J. M. M. Senovilla
In this lecture we will show some properties of a singularity-free solution to Einstein's equations and its accordance with some theorems dealing with singularities. We will also d…
Surface densities in General Relativity
F. J. Chinea, L. Fernández-Jambrina
In this lecture we deal with the construction of surface densities for the angular momentum of the sources of asymptotically flat vacuum stationary axisymmetric spacetimes. These s…
Differential Form Approach for Stationary Axisymmetric Maxwell Fields in General Relativity
L. Fernandez-Jambrina, F. J. Chinea
A formulation for stationary axisymmetric electromagnetic fields in general relativity is derived by casting them into the form of an anisotropic fluid. Several simplifications of…
Angular Momentum Surface Density of the Kerr Metric
L. Fernandez-Jambrina, F. J. Chinea
A method for interpreting discontinuities of the twist potential of vacuum stationary axisymmetric solutions of Einstein's equations is introduced. Surface densities for the angula…
