Isotropic submanifolds of pseudo-Riemannian spaces
(Elsevier, 2012-09)
The family of all the submanifolds of a given Riemannian or pseudo-Riemannian manifold is large enough to classify them into some interesting subfamilies such as minimal (maximal), totally geodesic, Einstein, etc. Most of ...

On the idempotency of some composite functors
(Springer, 2012-01)
We present examples of localization functors whose composition with certain cellularization functors is not idempotent, and vice versa.

Abelian subalgebras and ideals of maximal dimension in Lie algebras
(2012-03-27)
En esta tesis se han estudiado subálgebras e ideales abelianos de álgebras de Lie, considerando dos invariantes, llamados alfa y beta, que representan el máximo entre la dimensión de todas las subálgebras abelianas (ideales ...

Mujeres pioneras de la Matemática española
(Universidad de Almería, 2012-10-26)
En este artículo se muestran las biografías de dos mujeres españolas nacidas con bastante anterioridad al siglo en el que nos encontramos, prácticamente desconocidas para la sociedad aunque muy relevantes en matemáticas, ...

On manifolds with nonhomogeneous factors
(Springer, 2012-06)
We present simple examples of finite-dimensional connected homogeneous spaces (they are actually topological manifolds) with nonhomogeneous and nonrigid factors. In particular, we give an elementary solution of an old ...

Superando barreras a base de ingenio
(2012)
No hay la menor duda de que la mujer ha estado siempre muy discriminada con respecto al varón en el papel a desempeñar en todas las civilizaciones que se han desarrollado a lo largo de la historia, no comenzando a tener ...

Application of statistical techniques for comparing Lie algebra algorithms
(International Center for Scientific Research and Studies Publication, 2012-03)
This paper is devoted to study and compare two algebraic algorithms related to the computation of Lie algebras by using statistical techniques. These techniques allow us to decide which of them is more suitable and less ...

Consequences of some outerplanarity extensions
(Rocky Mountain Mathematics Consortium, 2012)
In this expository paper we revise some extensions of Kuratowski planarity criterion, providing a link between the embeddings of infinite graphs without accumulation points and the embeddings of finite graphs with ...
