An obstruction to represent abelian lie algebras by unipotent matrices
(2004)
The aim of this paper is the study of abelian Lie algebras as subalgebras of the nilpotent Lie algebra gn associated with Lie groups of upper-triangular square matrices whose main diagonal is formed by 1. We also give an ...

Some inequalities on totally real submanifolds in locally conformal Kaehler space forms
(Korean Mathematical Society, 2004)
In this article, we establish sharp relations between the sectional curvature and the shape operator and also between the k-Ricci curvature and the shape operator for a totally real submanifold in a locally conformal Kaehler ...

Representation theory of some infinite-dimensional algebras arising in continuously controlled algebra and topology
(Springer, 2004)
In this paper we determine the representation type of some algebras of infinite matrices continuously controlled at infinity by a compact metrizable space. We explicitly classify their finitely presented modules in the ...

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 ...

Álgebras admisibles e isoálgebras de Lie-Santilli (aplicación en mecánica clásica y cuántica)
(2004)
La teoría de admisibilidad en álgebras, introducida por Albert en 1948, ha resultado tener aplicación en diversos campos de la Mecánica Cuántica. En concreto, en relatividad especial, la cual resulta obsoleta en el instante ...

On generalized Sasakian-space-forms
(2004)
We study contact metric and trans-Sasakian generalized Sasakian-space-forms. We also give some interesting examples of generalized Sasakian-space-forms by using warped products and conformal changes of metric.

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, ...
