Singularly perturbed biharmonic problems with superlinear nonlinearities
(Khayyam PublishingAthens, 2014)
We are interested in finding a family of solutions of a singularly perturbed biharmonic equation, which has a concentration behavior. The proof is based on variational methods and uses a weak version of the Ambrosetti-Rabinowitz ...
Local solvability of elliptic equations of even order with Holder coefficients
(Unión Matemática Argentina, 2020-02)
We consider elliptic equations of order 2m with Hölder coefficients. We show local solvability of the Dirichlet problem with m conditions on the boundary of the upper half space. First we consider local solvability in free ...
Using weak forms to derive asymptotic expansions of elliptic equations with high-contrast cofficients
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Matemáticas, 2014-07-01)
In this work we review some recent results on approximation of solutions of elliptic problems with high-contrast coefficients. In particular, we detail the derivation of asymptotic expansions for the solution in terms of ...

Indicadores equilibrados de erro em funcional de interesse para aproximação de problemas elípticos e parabólicos pelo método de Galerkin descontínuo
(Universidade Federal de Santa CatarinaLondrinaBrasilPrograma de Pós-Graduação em Matemática Pura e AplicadaUFSC, 2018-03)
This thesis presents theoretical and practical results on equilibrated error indicators for functional of interest in the approximation of linear elliptic problems and linear and non-linear parabolic problems by the ...
Two Families Of H(div) Mixed Finite Elements On Quadrilaterals Of Minimal Dimension
(SIAM PublicationsPhiladelphia, 2016)
On a quasilinear elliptic problem involving the 1-biharmonic operator and a Strauss type compactness result
(2020-01-01)
In this paper we prove the compactness of the embeddings of the space of radially symmetric functions of BL(R N) into some Lebesgue spaces. In order to do so we prove a regularity result for solutions of the Poisson equation ...
