On the approximation of a virtual coarse space for domain decomposition methods in two dimensions 

Calvo Alpízar, Juan Gabriel (2018)
A new extension operator for a virtual coarse space is presented which can be used in domain decomposition methods for nodal elliptic problems in two dimensions. In particular, a two-level overlapping Schwarz algorithm is ...

Parallel Sums and Adaptive BDDC Deluxe 

Widlund, Olof B.; Calvo Alpízar, Juan Gabriel (2017)
There has recently been a considerable activity in developing adaptive methods for the selection of primal constraints for BDDC algorithms and, in particular, for BDDC deluxe variants. The primal constraints of a BDDC or ...

Implementación de una plataforma computacional para la solución de PDE's elípticas, mediante FEM y descomposición de dominios BDDC. 

Mora Cordero, Fabian (2019)
En este trabajo se desarrolla una plataforma computacional en C++-CUDA, la cual introduce una serie de estructuras de datos que simplifican el manejo de memoria en CUDA. En la plataforma también se introducen elementos de ...

A multilayer network model of Covid-19: implications in public health policy in Costa Rica 

Sánchez Peña, Fabio Ariel; Calvo Alpízar, Juan Gabriel; Mery, Gustavo; García Puerta, Yury Elena; Vásquez Brenes, Paola Andrea; Barboza Chinchilla, Luis Alberto; Pérez Rosales, María Dolores; Rivas, Tania (2022-05)
Successful partnerships between researchers, experts, and public health authorities have been critical to navigate the challenges of the Covid-19 pandemic worldwide. In this collaboration, mathematical models have played ...

Domain Decomposition Methods for Problems in H(curl) 

Calvo Alpízar, Juan Gabriel (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 ...

A BDDC algorithm with deluxe scaling for H(curl) in two dimensions with irregular subdomains 

Calvo Alpízar, Juan Gabriel (2015)
A bound is obtained for the condition number of a BDDC algorithm for problems posed in H(curl) in two dimensions, where the subdomains are only assumed to be uniform in the sense of Peter Jones. For the primal variable ...

A partial differential equation model with age-structure and nonlinear recidivism: Conditions for a backward bifurcation and a general numerical implementation 

Sánchez Peña, Fabio Ariel; Calvo Alpízar, Juan Gabriel; Segura Ugalde, Esteban; Feng, Zhilan (2019-12-15)
We formulate an age-structured three-staged nonlinear partial differential equation model that features nonlinear recidivism to the infected (infectious) class from the temporarily recovered class. Equilibria are computed, ...

Mathematical and Statistical models as tools for the control ofmosquito-borne diseases: The experience of Costa Rica 

Sánchez Peña, Fabio Ariel; Barboza Chinchilla, Luis Alberto; Vásquez Brenes, Paola Andrea; García Puerta, Yury Elena; Calvo Alpízar, Juan Gabriel; Chou Chen, Shu Wei; Mery, Gustavo (2021-06-25)
The modeling of infectious diseases provides valuable input in the development of mitigating strategies and implementation of public health interventions. We highlight results and current research conducted in Costa Rica ...

The role of short-term immigration on disease dynamics: An SIR model with age-structure
El rol de la inmigración en periodos cortos sobre la dinámica de enfermedades: un modelo sir con estructura de edad 

Sánchez Peña, Fabio Ariel; Calvo Alpízar, Juan Gabriel (2019-02-18)
We formulate an age-structured nonlinear partial differential equation model that features short-term immigration effects in a population. Individuals can immigrate into the population as any of the three stages in the ...

Dengue model with early-life stage of vectors and age-structure within host
Modelo de dengue con etapa temprana en vectores y estructura de edad en el huésped 

Sánchez Peña, Fabio Ariel; Calvo Alpízar, Juan Gabriel (2019-12)
We construct an epidemic model for the transmission of dengue fever with an early-life stage in the vector dynamics and age-structure within hosts. The early-life stage of the vector is modeled via a general function that ...
