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 ...
Comparative analysis of dengue versus chikungunya outbreaks in Costa Rica
(2018-06)
For decades, dengue virus has been a cause of major public health concern in Costa Rica, due to its landscape and climatic conditions that favor the circumstances in which the vector, Aedes aegypti, thrives. The emergence ...
On the one dimensional spectral Heat content for stable processes
(2016-09)
This paper provides the second term in the small time asymptotic expansion of the
spectral heat content of a rotationally invariant α-stable process, 0 < α ≤ 2, for the
bounded interval (a, b). The small time behavior ...

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 ...
Heat content estimates over sets of finite perimeter
(2016-09)
This paper studies by means of standard analytic tools the small time behavior of the heat content over a bounded Lebesgue measurable set of finite perimeter by working with the set covariance function and by imposing ...
On the Colmez conjecture for non-abelian CM fields
(2018-02-08)
The Colmez conjecture relates the Faltings height of an abelian variety with complex multiplication by the ring of integers of a CM field E to logarithmic derivatives of Artin L-functions at s=0. In this paper, we prove ...
