Comment on "From geodesics of the multipole solutions to the perturbed Kepler problem"
L. Fernández-Jambrina
In this comment we explain the discrepancies mentioned by the authors between their results and ours about the influence of the gravitational quadrupole moment in the perturbative…
-cosmological singularities
L. Fernández-Jambrina
In this paper we characterize barotropic index singularities of homogeneous isotropic cosmological models. They are shown to appear in cosmologies for which the scale factor is ana…
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…
Non-regular Potentials and Sources for Static Axisymmetric Electrovacs
L. Fernández-Jambrina
In this lecture a new formalism for constructing electromagnetic surface sources for static axisymmetric electrovacs is presented. The electrostatic and magnetostatic sources are d…
Magnetic Moment Density from Lack of Smoothness of the Ernst Potential
L. Fernández-Jambrina
In this talk it is shown a way for constructing magnetic surface sources for stationary axisymmetric electrovac spacetimes possessing a non-smooth electromagnetic Ernst potential.…
