XIX Simposio Internacional de Métodos Matemáticos Aplicados a las Ciencias
(2014-05-02)
El XIX° Simposio Internacional de Métodos Matemáticos Aplicados a las Ciencias (XIX SIMMAC) es el evento de matemática aplicada más importante de América Central. Es organizado por el Centro de Investigación en Matemática ...
Drinking as an epidemic - a simple mathematical model with recovery and relapse
(2007)
This chapter discusses a simple mathematical model of drinking lapse. Problem drinking is modeled as an acquired state - the result of frequent or intense interactions among individuals in three drinking states within a ...
Vertical Transmission in a Two-Strain Model of Dengue Fever
(2014)
The role of vertical transmission in vectors has rarely been addressed in the study of dengue dynamics and control, in part because it was not considered a critical population-level factor. In this paper, we apply the ...

The Gromov’s centralizer theorem for semisimple Lie group actions
(2017-10)
We give a new version of the Gromov’s centralizer theorem in the case
of semisimple Lie group actions and arbitrary rigid geometric structures of algebraic
type.
On the Ramanujan–Lodge harmonic number expansion
(2015-01-15)
The aim of this paper is to extend and refine the Ramanujan–Lodge harmonic number expansion into negative powers of a triangular number. We construct a faster asymptotic series and some new sharp inequalities for the ...
Analyzing the Measurement Equivalence of a Translated Test in a Statewide Assessment Program
Análisis de la equivalencia de la medida de la traducción de un test en un programa de evaluación estatal
(2016-09)
When tests are translated into one or more languages, the question of the equivalence of
items across language forms arises. This equivalence can be assessed at the scale level by means of
a multiple group confirmatory ...
Stora's fine notion of divergent amplitudes
(2016-11)
Stora and coworkers refined the notion of divergent quantum amplitude, somewhat upsetting the standard power-counting recipe. This unexpectedly clears the way to new prototypes for free and interacting field theories of ...
