Identification of the Source for Full Parabolic Equations
Guillermo Federico Umbricht
In this work, we consider the problem of identifying the time independent source for full parabolic equations in from noisy data. This is an ill-posed problem in the…
A Regularization Operator for the Source Approximation of a Transport Equation
Guillermo F. Umbricht, Diana Rubio, Claudio El Hasi
Source identification problems have multiple applications in engineering such as the identification of fissures in materials, determination of sources in electromagnetic fields or…
Anisotropic interpolation error estimate for arbitrary quadrilateral isoparametric elements
Gabriel Monzón
The aim of this paper is to show that, for any , the -anisotropic interpolation error estimate holds on quadrilateral isoparametric elements verifying th…
The minimal angle condition for quadrilateral finite elements of arbitrary degree
Acosta Gabriel, Monzon Gabriel
We study Lagrange interpolation error estimates for general quadrilateral finite elements with . For the most standard case of it turns ou…
High order methods for irreversible equations
Mariano De Leo, Diego Rial, Constanza Sanchez de la Vega
In this work, we show high order splitting methods of integration without negative steps, allowing us to solve numerically irreversible problems, like reaction-diffusion equations.…
Anisotropic mesh refinement in polyhedral domains: error estimates with data in L^2(Ω)
Thomas Apel, Ariel L. Lombardi, Max Winkler
The paper is concerned with the finite element solution of the Poisson equation with homogeneous Dirichlet boundary condition in a three-dimensional domain. Anisotropic, graded mes…
