Curvature of planar aesthetic curves
A. Cantón, L. Fernández-Jambrina, M. J. Vázquez-Gallo
Farin proposed a method for designing Bezier curves with monotonic curvature and torsion. Such curves are relevant in design due to their aesthetic shape. The method relies on appl…
Initial directional singularity in inflationary models
L. Fernandez-Jambrina
In [1] a new cosmological model is proposed with no big bang singularity in the past, though past geodesically incomplete. This model starts with an inflationary era, follows with…
Geometric elements and classification of quadrics in rational Bézier form
A. Cantón, L. Fernández-Jambrina, M. E. Rosado María +1
In this paper we classify and derive closed formulas for geometric elements of quadrics in rational Bézier triangular form (such as the center, the conic at infinity, the vertex an…
Grand Rip and Grand Bang/Crunch cosmological singularities
L. Fernández-Jambrina
The present accelerated expansion of the universe has enriched the list of possible scenarios for its fate, singular or not. In this paper a unifying framework for analyzing such b…
Cosmological singularities in FLRW spacetimes
L. Fernandez-Jambrina, R. Lazkoz
In this talk we review the appearance of new types of singularities (big rip, sudden singularities...) in FLRW cosmological models that have arisen on considering explanations for…
Multipole corrections to perihelion and node line precession
L. Fernández-Jambrina
In this talk relativistic corrections due to Geroch-Hansen multipoles for perihelion precession and node line precession of orbits in a stationary axially symmetric vacuum spacetim…
