Contributions to the continuity problem for Lyapunov exponents
(2018)
O objetivo deste trabalho é estudar a continuidade e a semi-continuidade dos expoentes de Lyapunov em dois contextos diferentes. O primeiro diz respeito a cociclos lineares sobre dinâmicas parcialmente hiperbólicas. É ...

Climate-Driven Statistical Models as Effective Predictors of Local Dengue Incidence in Costa Rica: A Generalized Additive Model and Random Forest Approach
Variables climáticas como predictores de la incidencia de dengue en Costa Rica: Un enfoque de modelo aditivo generalizado y bosques aleatorios
(2019-12)
Climate has been an important factor in shaping the distribution and incidence of dengue cases in tropical and subtropical countries. In CostaRica, a tropical country with distinctive micro-climates, dengue has been endemic ...
Estudio de una definición no aritmética de finitud conjuntista
(1987)
Intuitivamente, un conjunto es finito si termina quedando vacío al extraerle elementos de uno en uno. El propósito de este trabajo es formalizar esta noción de finitud conjuntista y discutir algunas propiedades que se ...
Analysis of a vorticity–based fully–mixed formulation for 3D Brinkman–Darcy problem.
(2016)
We propose and analyze a fully-mixed finite element method to numerically approximate the flow patterns of a viscous fluid within a highly permeable medium (an array of low concentration fixed particles), described by ...
Characterization of two-parameter matrix valued BMO by commutator with the Hilbert Transform
(2018)
In this paper, we prove that the space of two parameter matrix-valued BMO functions can be characterized by considering iterated commutators with the Hilbert transform. The upper estimate relies on Petermichl's representation ...
Domain Decomposition Methods for Problems in H(curl)
(2015-05)
Two domain decomposition methods for solving vector field problems posed in H(curl) and discretized with Nedelec finite elements are considered. These finite elements are conforming in H(curl). A two-level overlapping ...
Climate-based descriptive models of dengue fever: The 2002 epidemic in Colima, Mexico
(2006-06)
Dengue is a public health problem on the rise in many tropical regions and affects approximately 100 million people every year worldwide. In this paper, the authors retrospectively assess the association between five ...
