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

Semilinear elliptic equations with dependence on the gradient

open access: yesElectronic Journal of Differential Equations, 2012
In this article we consider elliptic equations whose nonlinear term depends on the gradient of the unknown. We assume that the nonlinearity has a asymptotically linear growth at zero and at infinity with respect to the second variable.

Bifurcations for semilinear elliptic equations with convex nonlinearity

open access: yesElectronic Journal of Differential Equations, 1999
We investigate the exact number of positive solutions of the semilinear Dirichlet boundary value problem $Delta u+f(u) = 0$ on a ball in ${mathbb R}^n$ where $f$ is a strictly convex $C^2$ function on $[0,infty)$. For the one-dimensional case we classify
