On the Keldys-Fichera boundary-value problem for degenerate quasilinear elliptic equations

Electronic Journal of Differential Equations, 2002
We prove existence and uniqueness theorems for the Keldys-Fichera boundary-value problem using pseudo-monotone operators. The equation studied here is quasilinear, elliptic, and its set of degenerate points may be of non-zero measure.

Existence and concentration of positive solutions for a quasilinear elliptic equation in R

Electronic Journal of Differential Equations, 2010
We study the existence and concentration of positive solutions for the quasilinear elliptic equation $$ -varepsilon^2u'' -varepsilon^2(u^2)''u+V(x) u = h(u) $$ in $mathbb{R}$ as $varepsilono 0$, where the potential $V:mathbb{R}o mathbb{R}$ has a ...

The eigenvalue problem for a singular quasilinear elliptic equation

Electronic Journal of Differential Equations, 2004
We show that many results about the eigenvalues and eigenfunctions of a quasilinear elliptic equation in the non-singular case can be extended to the singular case. Among these results, we have the first eigenvalue is associated to a $C^{1,alpha}(Omega)$
