Una propuesta para enseñar geometría proyectiva en la formación de profesores de matemática
Revista de Educação Matemática, 2021 En esta propuesta presentamos algunos resultados de Geometría Proyectiva que consideramos podrían formar parte de la formación de profesores de matemática. La geometría proyectiva resulta una teoría no elemental – como podría serlo la geometría sintética

A footnote to a theorem of Kawamata
Mathematische Nachrichten, Volume 296, Issue 10, Page 4739-4744, October 2023., 2023 Abstract Kawamata has shown that the quasi‐Albanese map of a quasi‐projective variety with log‐irregularity equal to the dimension and log‐Kodaira dimension 0 is birational. In this note, we show that under these hypotheses the quasi‐Albanese map is proper in codimension 1 as conjectured by Iitaka.

Curves in the Lorentz-Minkowski plane: elasticae, catenaries and grim-reapers
Open Mathematics, 2018 This article is motivated by a problem posed by David A. Singer in 1999 and by the classical Euler elastic curves. We study spacelike and timelike curves in the Lorentz-Minkowski plane 𝕃2 whose curvature is expressed in terms of the Lorentzian ...

On the structure vector field of a real hypersurface in complex quadric
Open Mathematics, 2018 From the notion of Jacobi type vector fields for a real hypersurface in complex quadric Qm we prove that if the structure vector field is of Jacobi type it is Killing when the real hypersurface is either Hopf or compact.
