Modelos mixtos para datos composicionales: Una aplicacion con resultados electorales en Colombia
(Universidad Santo TomásPregrado EstadísticaFacultad de Estadística, 2017)
The present work consists in the application of certain tools developed for the analysis of the compositional
data. The purpose includes the revision of the theoretical aspects; the geometry of the simplex,
the log-ratio ...
Aplicación del método variacional a los problemas de Dirichlet y Neumann
Las ecuaciones diferenciales parciales (E.D.P.), en particular han contribuido al modelamiento de fenómenos naturales desde diferentes metodologías, justificando de paso el esfuerzo de las matemáticas para crear teorías y ...
Gaussian distribution of trie depth for strongly tame sources
(Cambridge University Press, 2015-01)
The depth of a trie has been deeply studied when the source which produces the words is a simple source (a memoryless source or a Markov chain). When a source is simple but not an unbiased memoryless source, the expectation ...
An eigenvalue problem for the biharmonic operator on Z(2)-symmetric regions
(CAMBRIDGE UNIV PRESS, 2008)
In this work we show that the eigenvalues of the Dirichlet problem for the biharmonic operator are generically simple in the set Of Z(2)-symmetric regions of R-n, n >= 2, with a suitable topology. To accomplish this, we ...
On a Rankin-Selberg convolution of two variables for Siegel modular forms
(Walter de Gruyter and Co., 2003)
In this article we study a Rankin-Selberg convolution of two complex variables attached to Siegel modular forms of degree 2. We establish its basic analytic properties, find its singular curves and compute some of its ...
On regularly varying functions with applications to functions theory
(Universidad Nacuional de Colombia; Sociedad Colombiana de matemáticas, 1981)
Se estudia el comportamiento asintótico de funciones positivas no decrecientes de orden p, con respecto a funciones de variación regular de índice p, es decir funciones p-homogéneas en el límite esto es R(∝x)/R(x) →∝P ...
Infinitos números de Carmichael
(Universidade Federal de Minas GeraisUFMG, 2013-04-24)
The goal of this work is to show that there are infinitely many Carmichael numbers. Hence, the Carmichael numbers are in some way the worst numbers for testing primality using Fermats Little Theorem. Thus, Fermats Little ...
