    • A mixed virtual element method for the Brinkman problem 

      Sequeira, Filander; Cáceres, Ernesto; Gatica, G.N. (Mathematical Models and Methods in Applied Sciences vol.27 no.4 707-743 2017, 2017)
      In this paper, we introduce and analyze a mixed virtual element method (mixed-VEM) for the two-dimensional Brinkman model of porous media flow with non-homogeneous Dirichlet boundary conditions. More precisely, we employ ...

    • A priori and a posteriori error analyses of a pseudostress-based mixed formulation for linear elasticity 

      Sequeira, Filander; Gatica, Gabriel N.; Gatica, Luis F. (Computers and Mathematics with Applications vol.71 no.2 585-614 2016, 2016-01-02)
      In this paper we present the a priori and a posteriori error analyses of a non-standard mixed finite element method for the linear elasticity problem with non-homogeneous Dirichlet boundary conditions. More precisely, the ...

    • Abelian covers of alternating groups 

      Ramirez, Jeremias; Barrantes, Daniel (Archiv der Mathematik 107 135-150, 2016-07-07)
      Let G = A n , a finite alternating group. We study the commuting graph of G and establish, for all possible values of n barring 13, 14, 17, and 19 whether or not the independence number is equal to the clique-covering number.

    • The challenges of mathematics education for Indigenous teacher training 

      Gavarrete Villaverde, María Elena (Intercultural Education, 2015-12-15)
      In this article, I outline research carried out on in an Ethnomathematics course designed to train Indigenous teachers in Costa Rica, in which the following ethnic groups participated: Ngabes, Bribris, and Cabecares. The ...
