Some advances in the research on Lie algebras
(2008)
The main goal of this poster, which is written in the form of a survey and tries to show some aspects of the research of authors on Lie algebras, is to pay homage to the memory of Pilar Pisón Casares, who was firstly teacher ...

Aventura matemática: Búsqueda del tesoro en Isla Mágica
(2007-11)
Durante la fase regional de la XXII Olimpiada Matemática Thales, se realizaron tres pruebas por equipos, aparte de la tradicional prueba individual. De todas ellas, la que generó más expectativas entre los 42 chicos y ...

El papel de las webquest en las NTIC
(2008-07)
La ponencia que aquí se presenta persigue un triple objetivo. Por una parte, mostrarle al lector en general, y al profesorado de Secundaria y Bachillerato en particular, el concepto de WebQuest (WQ) y sus principales ...

Decomposition of principal autotopisms into triples of a Latin square
(2006)
Triples of a Latin square L and isotopisms of its autotopism group U (L) can be used to get a secret sharing scheme in Cryptography. Although the weight of in formation given by the latter is usually greater than that given ...

Santilli's autotopism of associative partial quasigroups
(International Academic Press, 2007)
In this paper, given an isotopism Θ ∈ In, we study some properties of the set SAPLS(Θ) of those partial Latin squares being the multiplication table of an associative partial quasigroup having Θ as a Santilli’s autotopism.

Determinants of latin squares of a given pattern
(2008-07)
Cycle structures of autotopisms of Latin squares determine all possible patterns of this kind of design. Moreover, given any isotopism, the number of Latin squares containing it in their autotopism group only depends on ...

Latin squares associated to principal autotopisms of long cycles. Application in Cryptography
(2006-04)
Fixed a principal isotopism $\Theta=(\alpha,\beta,\epsilon)\in S_n^3$, where $S_n$ is the symmetric group of the set $N=\{0,1,...,n-1\}$, we are going to study in this paper the number $\Delta(\Theta)$ of Latin squares ...

0/1-Polytopes related to Latin squares autotopisms
(2008)
The set LS(n) of Latin squares of order n can be represented in Rn3 as a (n−1)3-dimensional 0/1-polytope. Given an autotopism Θ=(α,β,γ)∈An, we study in this paper the 0/1-polytope related to the subset of LS(n) having Θ ...

Conceptos básicos sobre isocriptografía siguiendo el modelo MCIM
(Universidad Politécnica de Madrid, 2004)
Una de las aplicaciones prácticas de la isoteoría de Santilli que ha surgido en los últimos años se refiere al campo de la criptografía. Generalizando la unidad utilizada en los criptogramas se originan una nueva clase ...

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, ...
