Singularities in inflationary cosmological models
L. Fernández-Jambrina
Due to the accelerated expansion of the universe, the possibility of formation of singularities has changed from the classical Big Bang and Big Crunch singularities to include a nu…
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…
