On the stability of certain perturbed systems of differential equations and the relationship with the magnitude of the perturbation
Sobre la estabilidad de ciertos sistemas perturbados de ecuaciones diferenciales y sus relaciones con la magnitud de la perturbación
(2010-04-16)
In this work we consider a class of polytopes of third order squarematrices, studied early. We obtain a condition to guarantee Hurwitzstability of each of elements of the polytope. This condition is moresimples than one ...
A Non-Standard Generating Function for Continuous Dual q-Hahn polynomials
Una Función Generatriz no Estandar para Polinomios q-Hahn Duales Continuos
(2011-03-18)
We study a non-standard form of generating function for the three-parameter continuous dual q-Hahn polynomials $p_{n} (x; a, b, | q)$, which has surfaced in a recent work of the present authors on the construction of lifting ...
Propiedades de un enfoque difuso para particionamiento con datos bimodales
Propiedades de un enfoque difuso para particionamiento con datos bimodales
(2010-04-09)
It is presented a new fuzzy partitioning criterion for two-mode data and an algo-rithm is formulated for its optmization. We study the convergence properties of themethod. The method was tested on real data. It is ...
Presentación e implementación del método de nubes dinámicas difuso
(2009-02-18)
Se hace una presentación del método de Nubes Dinámicas Difuso considerando la variante del centro de gravedad (Forgy, 1965). La clasificación difusa obtenida se usa como herramienta de validación para establecer el número ...
Optimiza - un paquete computacional para la optimización de problemas no lineales
Optimiza - un paquete computacional para la optimización de problemas no lineales
(2009-02-18)
Our goal is to build a software able to solve problems in non linear optimization. A central point is selection of the algorithm, which is based on Augmented Lagrangian Method combined with quasi-Newton methods (BFGS, ...

Isomorfismo de Conjuntos de Relaciones
(2012-04-26)
It is recommended to use a solving method for relations sets in order to solve the isomorphism problem. This method allows to solve the same problem for big size graphs, homogeneous graphs, graph systems, k-signs logic ...

Sobre el Teorema Tauberiano de W. Rudin
(2012-03-28)
Using W. Rudin’s method it is shown that the tauberian theorem can be generalized to several kernels other than the Poisson kernel. We also proof an inverse of the tauberian theorem, that is, an abelian theorem.

Equilibrio walrasiano en economías de intercambio
(2009-02-18)
We present the aggregated excess demand functions in an exchange economy. We study the properties and the equilibrium price vector of the aggregated excess demand functions. We prove that the walrasian equilibrium is a ...

Definición de semiproductos escalares útiles en análisis de datos
(2009-02-20)
We develop the theory necessary for Data Analysis with inner semiproducts, extendingtha classical concepts of inner products usually employed. For this, we usethe basic algebraic definitions of non degenerated bilinear ...
Convergence in nonlinear systems with a forcing term
(2009-02-18)
The problem of convergence, as t ® +¥ , of solutions of the system (1) is considered. It is assumed that the functions a , f and g are of class C1 for all values of their arguments, furtermore g' (x) > 0 , f ' (x) ³ r > ...
