Semilinear Elliptic Equations in Unbounded Domains [PDF]

open access: yes, 2004
We studied some semilinear elliptic equations on the entire space R^N. Our approach was variational, and the major obstacle was the breakdown in compactness due to the unboundedness of the domain. First, we considered an asymptotically linear Scltrodinger equation under the presence of a steep potential well.

Inverse eigenvalue problems for semilinear elliptic equations

open access: yesElectronic Journal of Differential Equations, 2009
We consider the inverse nonlinear eigenvalue problem for the equation $$displaylines{ -Delta u + f(u) = lambda u, quad u > 0 quad hbox{in } Omega,cr u = 0 quad hbox{on } partialOmega, } where $f(u)$ is an unknown nonlinear term, $Omega subset ...

Multiple solutions of nonlinear fractional elliptic equations via Morse theory

open access: yesElectronic Journal of Differential Equations, 2017
This article concerns the existence and multiplicity of weak solutions of the nonlinear fractional elliptic problem. We extend some well known results of semilinear Laplacian equations to the nonlocal fractional setting. Using the variational methods

A Second look at the first result of Landesman-Lazer type

open access: yesElectronic Journal of Differential Equations, 2000
We discuss some results concerning periodic and almot periodic solutions of ordinary differential equations which are precursors of a result on weak solutions of a semilinear elliptic boundary due to E. M. Landesman and the author. It is observed that in
