Goal problems in gambling theory
Goal problems in gambling theory
(2009-02-18)
A short introduction to goal problems in abstract gambling theory is given, along with statementes of some of the main theorems and a number of examples, open problems and references. Emphasis is on the finite-state, ...
El espacio cociente y algunas propiedades geométricas de los espacios de Banach
El espacio cociente y algunas propiedades geométricas de los espacios de Banach
(2009-02-18)
We state some geometric properties of Banach spaces, such as uniformly convex spaces, uniformly non-square spaces, local uniformly convex spaces, strictly convex spaces, etc., and we analyze the problem of translating such ...
La teoría de respuesta a los itemes: una moderna alternativa para el análisis psicométrico de instrumentos de medición
(2009-02-19)
La Teoría de Respuesta a los Itemes, TRI, (o "Item Response Theory", en inglés) es un enfoque más poderoso que la Teoría Clásica de los Tests para el análisis de calidad técnica de instrumentos de medición psicométricos. ...
A dichotomous property of the total variation of a process with independent increments
(2009-02-19)
We establish a property for the total variation of a cad-lag process with independent increments wich is dichotomous in the sense that only two alternatives are possible. For this purpose we introduce the methods of ...
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 ...
Detecting constraint redundancy in 0-1 linear programming problems
Detecting constraint redundancy in 0-1 linear programming problems
(2009-02-19)
In this paper we present a procedure for obtaining upper bounds on a linear function by means of certain families of packings, coverings and special ordered sets. We also present a new method for detecting redundant ...
On the Distribution of non-attacking Bishops on a Chessboard C
On the Distribution of non-attacking Bishops on a Chessboard C
(2012-04-26)
It is shown how the placement of non-attacking bishops on a chessboard C is related to the matching polynomial of a bipartite graph. Reduction algorithms for finding the bishop polynomial of C are given. We interpret ...
A method for analyzing turbulence models
(2009-02-19)
In this article we introduce a concept based on the differential constraints methodto examine the closure procedure in Turbulence Models. We show how this conceptmay be applied to study the problem of interaction and mixing ...
Circular chains of chinese dice
Cadenas circulares de dados chinos
(2010-04-16)
In this paper we study Chinese dice, mathematical objects similar to ordinary dice but allowing repetition among their face values.We say that a die A is preferred over a die B (written A B) if A wins more frequently ...

Análisis de Componentes Principales y Análisis de Regresión para Datos Categóricos. Aplicación en la Hipertensión Arterial.
(2010-07-02)
The present work is about the statistical processing of categorical data. The mathematical details of the Categorical Principal Components and the Categorical Regression Analysis are explained.The combination of both ...
