Bezier developable surfaces
L. Fernández-Jambrina
In this paper we address the issue of designing developable surfaces with Bezier patches. We show that developable surfaces with a polynomial edge of regression are the set of deve…
Interpolation of a spline developable surface between a curve and two rulings
A. Cantón, L. Fernández-Jambrina
In this paper we address the problem of interpolating a spline developable patch bounded by a given spline curve and the first and the last rulings of the developable surface. In o…
-singularities in cosmological models
L. Fernández-Jambrina
Recently a new type of cosmological singularity has been postulated for infinite barotropic index in the equation of state of the cosmological fluid, but vanishing pres…
Hidden past of dark energy cosmological models
L. Fernandez-Jambrina
In this paper we analyse the possibility of having homogeneous isotropic cosmological models with observers reaching in finite proper time. It is shown that just observa…
Magnetic Surfaces in Stationary Axisymmetric General Relativity
L. Fernandez-Jambrina
In this paper a new method is derived for constructing electromagnetic surface sources for stationary axisymmetric electrovac spacetimes endowed with non-smooth or even discontinuo…
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…
