Minimal covers of open manifolds with half-spaces and the proper L-S category of product spaces
(Belgian Mathematical Society, 2002-09)
Classical results about the Lusternik-Schnirelmann category of product spaces have their analogues in the category of proper maps. By comparing the proper Lusternik-Schnirelmann category of an open manifold X with ...

Classification of asexual diploid organisms by means of strongly isotopic evolution algebras defined over any field
(Elsevier, 2017-02-15)
Evolution algebras were introduced into Genetics to deal with the mechanism of inheritance of asexual organisms. Their distribution into isotopism classes is uniquely related with the mutation of alleles in nonMendelian ...

Did Fátima de Madrid really exist?
(LAR Centre Press, 2016-02)
In this paper we firstly pose the question of whether Fátima de Madrid, a Spanish mathematician woman allegedly born in Madrid, X-XI centuries, really existed or, on the contrary, she is only a product of the imagination ...

Muchos siglos antes de Hipatia ya hubo mujeres matemáticas
(2010)
Evidentes razones mediáticas (película Ágora de 2009, biografías, documentales...), unidas a razones ciertamente científicas (obra geométrica, estudio de las secciones cónicas…) han convertido la vida de Hipatia de ...

Bi-slant submanifolds of para Hermitian manifolds
(MDPI, 2019-07-11)
In this paper, we introduce the notion of bi-slant submanifolds of a para Hermitian manifold. They naturally englobe CR, semi-slant, and hemi-slant submanifolds. We study their first properties and present a whole gallery ...

Mutation graphs of asexual diploid organisms
(2017-07)
The mutation graph of an asexual diploid organism is introduced as an edgecolouredgraph derived from the genetic pattern by isotopisms of an evolution algebraover a finite field. We describe the step-by-step construction ...

B.-Y. Chen's inequality for submanifolds of generalized space forms
(Indian National Science Academy, 2007-06)
In this article, we investigate sharp inequalities involving δ-invariants for submanifolds in both generalized complex space forms and generalized Sasakian space forms, with arbitrary codimension.
