A two-level overlapping Schwarz method for H(curl) in two dimensions with irregular subdomains
(2015-10-07)
A bound is obtained for the condition number of a two-level overlapping Schwarz algorithm for problems posed in H(curl) in two dimensions, where the subdomains are only assumed to be John subdomains. The coarse space is ...
An adaptive choice of primal constrains for BDDC domain decomposition algorithms
(2016-12-12)
An adaptive choice for primal spaces based on parallel sums is developed for BDDC deluxe methods and elliptic problems in three dimensions. The primal space, which forms the global, coarse part of the domain decomposition ...

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 ...
Improved Automatic Centerline Tracing for Dendritic and Axonal Structures
(2015-04)
Centerline tracing in dendritic structures acquired from confocal images of neurons is an essential tool for the construction of geometrical representations of a neuronal network from its coarse scale up to its fine scale ...
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 ...
Stratifications on the Moduli Space of Higgs Bundles
(2016-11-02)
The moduli space of Higgs bundles has two stratifications. The Bia lynickiBirula stratification comes from the action of the non-zero complex numbers by multiplication on the Higgs field, and the Shatz stratification arises ...
The Error in an Alternating Series
(2018-03)
We present a new proof of Johnsonbaugh’s estimates for the error in an alternating series based on an idea of R. M. Young. We also use this same idea to prove the convergence of the Euler transform and a corresponding error ...

Didactical proposal for teaching polynomial equations at university level
(2017)
En este artículo contiene los principales resultados obtenidos a partir del diseño, aplicación y evaluación de una propuesta didáctica para la enseñanza de las ecuaciones polinomiales, la cual se desarrolló durante el mes ...
La geometría en su contexto histórico
(Las Matemáticas y su Enseñanza 6(17):21–34, 1995 octubre, 1995-10-15)
La geometría en los sistemas de enseñanza media ha sido retomado por diversas propuestas para remozar los programas de matemáticas; y en el caso de Costa Rica, con la puesta en práctica de un programa ambicioso que destaca ...
