Approximate controllability of a semilinear elliptic problem with robin condition in a periodically perforated domain
(Texas State University, 2017)
In this article, we study the approximate controllability and home-genization results of a semi-linear elliptic problem with Robin boundary condition in a periodically perforated domain. We prove the existence of minimal ...
An existence result for a linear-superlinear elliptic system with Neumann boundary conditions
(Academic Press Inc Elsevier ScienceSan DiegoEUA, 2006)
Approximate controllability and homogenization of a semilinear elliptic problem
(2003)
The L2- and H1-approximate controllability and homogenization of a semilinear elliptic
boundary-value problem is studied in this paper. The principal term of the state equation has rapidly
oscillating coefficients and ...
Effects of varying curvature and width on the electronic states of GaAs quantum rings
(Sociedade Brasileira de Física, 2006-06-01)
Stationary states of an electron in thin GaAs elliptical quantum rings are calculated within the effective-mass approximation. The width of the ring varies smoothly along the centerline, which is an ellipse. The solutions ...

A Posteriori Error Estimates for Lumped Mass Finite Element Method for Linear Parabolic Problems Using Elliptic Reconstruction
(TAYLOR & FRANCIS INC, 2017)
We study residual-based a posteriori error estimates for both the spatially discrete and the fully discrete lumped mass finite element approximation for parabolic problems in a bounded convex polygonal domain in (2). In ...
An elliptic singular system with nonlocal boundary conditions
(Elsevier, 2012-10)
We study the existence of solutions for the nonlinear second order elliptic system ∆u + g(u) = f(x), where g ∈ C(R N \ S, R N ) with S ⊂ R N bounded. Using topological degree methods, we prove an existence result under a ...
