An elliptic equation with no monotonicity condition on the nonlinearity
ESAIM: Control, Optimisation and Calculus of Variations, Tome 12 (2006) no. 4, pp. 786-794.

An elliptic PDE is studied which is a perturbation of an autonomous equation. The existence of a nontrivial solution is proven via variational methods. The domain of the equation is unbounded, which imposes a lack of compactness on the variational problem. In addition, a popular monotonicity condition on the nonlinearity is not assumed. In an earlier paper with this assumption, a solution was obtained using a simple application of topological (Brouwer) degree. Here, a more subtle degree theory argument must be used.
