(2009-02-20)
In this paper we study a general equilibrium model for economies with activitiesanalysis production technologies and we prove a global index theorem for regulareconomies.Keywords: Regular economy, economic equilibrium, ...
Lemniscatas 3D
Lemniscatas 3D
(2009-02-20)
A 3D lemniscate is a surface consisting of all points whose product of distances toa (finite) set of points or foci is constant. We introduce 3D lemniscates in the contextof geometric modelling and consider its deformation, ...

Some Ornstein-Uhlenbeck potentials for the one-dimensional Schrödinger operator part II: position-dependent drift
(2009-02-20)
Se considera el operador de Schr¨odinger en el c´?rculo unitario, con un potencial detipo Ornstein – Uhlenbeck, cuyo factor tendencial depende de la posici´on. Se describela distribuci´on del primer valor propio peri´odico, ...

Sobre los números de Hal y Lah
(2009-02-20)
In this article we study some properties concerning the Hal (H kn ) and Lah numbers(Lkn ), which are those that arise in the theory of combinatorics in association with the‘upward and downward factorial polynomials’ [x]n ...
Preference structures, choice functions and their logical form
Preference structures, choice functions and their logical form
(2009-02-20)
Binary relations and choice functions are two different tools for describing DMpreferences on a finite set of alternatives. Normal choice functions are the link betweenthese two tools. These choice functions are easily ...
Generación de métricas en análisis de datos
(2009-02-20)
In this work we introduce primary generators of metrics, that consist of linearcombinations of known metrics. We establish some theoretical properties of these generators,related to the computation of principal components, ...

Aproximación fractal para semivariogramas freáticos
(2009-02-20)
Hausdorff’s measure is integrated upon, and H¨older’s exponent is obtained as thecodimension DT ? D of the fractal in the Euclidian space in which it is immersed.This has resulted from the application of Daniell’s integral ...
The Determinant of Matching Matrix in the Evaluation of Matching Polynomial
The Determinant of Matching Matrix in the Evaluation of Matching Polynomial
(2011-04-29)
A characterization is given for graphs whose matching polynomial is the determinant of their matching matrices. The matching matrix is then modified and its relation with other graph polynomials is examined.
