Patches of developable surfaces bounded by NURBS curves
L. Fernandez-Jambrina
In this talk we review the problem of constructing a developable surface patch bounded by two rational or NURBS (Non-Uniform Rational B-spline) curves.
New futures for cosmological models
L. Fernández-Jambrina, R. Lazkoz
The discovery of accelerated expansion of the universe opened the possibility of new scenarios for the doom of our spacetime, besides aeternal expansion and a final contraction. In…
Flux through a Möbius strip?
L. Fernandez-Jambrina
Integral theorems such as Stokes' and Gauss' are fundamental in many parts of Physics. For instance, Faraday's law allows computing the induced electric current on a closed circuit…
Characterisation of rational and NURBS developable surfaces in Computer Aided Design
Leonardo Fernandez-Jambrina
In this paper we provide a characterisation of rational developable surfaces in terms of the blossoms of the bounding curves and three rational functions , , . Properties…
Equation of state and singularities in FLRW cosmological models
L. Fernandez-Jambrina, R. Lazkoz
We consider FLRW cosmological models with standard Friedmann equations, but leaving free the equation of state. We assume that the dark energy content of the universe is encoded in…
Classification of cosmological milestones
L. Fernandez-Jambrina, R. Lazkoz
In this paper causal geodesic completeness of FLRW cosmological models is analysed in terms of generalised power expansions of the scale factor in coordinate time. The strength of…
