Las WebQuest como herramienta de apoyo para el profesor de Matemáticas de Secundaria y Bachillerato
(Real Sociedad Matemática Española, 2009)
En este artículo se presenta una visión global de lo que se entiende por WebQuest (WQ en lo sucesivo) y se muestra su posible utilización por el profesor de Matemáticas de Secundaria y de Bachillerato para motivar al ...

The contact Whitney sphere
(Università del Salento, 2001)
In this paper, we introduce the contact Whitney sphere as an imbedding of the n-dimensional unit sphere as an integral submanifold of the standard contact structure on R2n+1. We obtain a general inequality for integral ...

Minimal slant submanifolds of the smallest dimension in S-manifolds
(European Mathematical Society, 2005)
We study slant submanifolds of S-manifolds with the smallest dimension, specially minimal submanifolds and establish some relations between them and anti-invariant submanifolds in S-manifolds, similar to those ones proved ...

On the connectivity of skeletons of pseudomanifolds with boundary
(Mathematical Institute, Academy of Sciences of the Czech Republic, 2002)
In this note we show that 1-skeletons and 2-skeletons of n-pseudomanifolds with full boundary are (n+ 1)-connected graphs and n-connected 2-complexes, respectively. This generalizes previous results due to Barnette and Woon.

Θ-critical sets of Latin squares having Θ as a principal autotopism
(2006)
Any principal autotopism Θ of a Latin square L ∈ LS(n), whose elements are in a set N of n symbols, gives a significant information about the symmetry of L. Although Θ-critical sets of L can be then used in Cryptography ...

Critical elements of proper discrete Morse functions
(Editorial Board of Mathematica Pannonica, 2008)
The aim of this paper is to study the notion of critical element of a proper discrete Morse function defined on non-compact graphs and surfaces. It is an extension to the non-compact case of the concept of critical simplex ...

Basic concepts on Lorentz simmetry and Minkowsky isogeometry by using the MCIM isotopic model
(2004-09)
At 1978, R.M. Santilli proposed to generalize the conventional Lie theory by using isotopies. To do it, he considered that the basic unit of any mathematical structure can depend on external factors (such as positions, ...
