An alternative correlation dimension statistic
(Centro de Investigación y Docencia Económicas, División de Economía, 1998)
One of the problems plaguing these applications has been the large data requirements of these statistical procedures. Time series numbering 20,000 are common in physical science applications, while results of applications ...
Sectorial public power and endogenous growth
(Centro de Investigación y Docencia Económicas, División de Economía, 1998)
The concept of sectorial political economy is defined using a model of fragmented perfect competition and introduced in an dynamic game in which the government is a Stackelberg leader and the representative families of ...
Endogenous planning horizons: distribution and growth
(Centro de Investigación y Docencia Económicas, División de Economía, 1998)
Endogenous growth models havea peculiarly unsatisfactory flavor when considered from the point of view of the less developed economies. According to these models, poor countries have a higher propensity to save then rich, ...
Immobilization of n-dimensional geometrical figures
(Centro de Investigación y Docencia Económicas, División de Economía, 1998)
We treat for n-dimensional bodies the immobilization problem introduced by Kuperberg and Papadimitriou, giving the zerocth, first and second order condition for fixing, as well as a geometric characterization of the first ...
The Kuperberg conjecture is true in two dimensions: any strictly compact C2 figure can be fixed firmly by three points unless it is the disk
(Centro de Investigación y Docencia Económicas, División de Economía, 1998)
We treat the immobilization problem introduced by Kuperberg and Papadimitriou in the case of two dimensional strictly convex figures, proving a strong version of the Kuperberg conjecture, any C2 strictly convex figure ...
A characteristic polynomial factorization: extending some matrix eigenvalue estimates
(Centro de Investigación y Docencia Económicas, División de Economía, 1998)
In this article we present several matrix theorems. The first of these, the theorem on Mondriga matrices, originated in the study of the immobilization of plane and solid figures in Euclidean space by points on their ...
Immobilization of solids and mondriga quadratic forms
(Centro de Investigación y Docencia Económicas, División de Economía, 1998)
Immobilization questions come from robotics, especially from grasping problems [5], [6]. In [1], a curvature criterion was established to decide when three points immobilize a plane figure. This curvature criterion proves ...
Puntos que fijan un cuerpo bajo isometrías
(Centro de Investigación y Docencia Económicas, División de Economía, 1998)
Consideramos algún cuerpo en el espacio de n dimensiones y lo sujetamos deteniéndolo de n + 1 puntos situados sobre su superficie. ¿Bajo qué condiciones queda sujeto el cuerpo? Distinguimos en primer término las condiciones ...
The correlation dimension ratio: comparison with the DBS statistic
(Centro de Investigación y Docencia Económicas, División de Economía, 1998)
In "An Alternative Correlation Statistic", the author compares the Correlation Dimension Ratio (CDR) with Grassberger and Procaccia's Correlation Dimension, (CD) showing it to be equally useful for distinguishing between ...
Solución numérica del problema de Ramsey mediante la ecuación del calor
(Centro de Investigación y Docencia Económicas, División de Economía, 1998)
El objetivo de este trabajo es aplicar al problema de Ramsey un método de solución numérica que se generalice fácilmente a un número mayor de variables. Transformamos el sistema de dos ecuaciones ordinarias de primer orden ...
