The numerical solution of the Dirichlet problem for the Helmholtz equation
(Pergamon-elsevier Science LtdOxfordInglaterra, 1996)
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 ...
A numerical scheme based on mean value solutions for the Helmholtz equation on triangular grids

On the existence of weak solutions of semilinear elliptic equations and systems with Hardy potentials
(Academic Press Inc., 2019)
© 2018 Elsevier Inc.Let Ω⊂RN (N≥3) be a bounded C2 domain and δ(x)=dist(x,∂Ω). Put Lμ=Δ+[Formula presented] with μ>0. In this paper, we provide various necessary and sufficient conditions for the existence of weak ...
Soluciones positivas para problemas elípticos sublineales y singulares
(2018-03)
En esta tesis se estudiaron tres problemas relacionados a ecuaciones de reacción difusión elípticas sublineales y singulares cuando el término de reacción cambia de signo. En primer lugar se trató la existencia y no ...
The beginning of the Fucik spectrum for the p-Laplacian
(Academic Press IncSan DiegoEUA, 1999)
