Abstract

In this paper we are going to show the existence of a nontrivial solution to the following model problem, {Δ(u)=2uln(1+u2)+u21+u22u+usin(u)a.e.onΩuη=0a.e.onΩ.}\{\begin{array}{lll} - \Delta (u) = 2uln(1+u^2)+\frac{|u|^2}{1+u^2}2u+usin(u) {a.e. on} \Omega \frac{\partial u}{\partial \eta} = 0 {a.e. on} \partial \Omega. \end{array} \} As one can see the right hand side is superlinear. But we can not use an Ambrosetti-Rabinowitz condition in order to obtain that the corresponding energy functional satisfies (PS) condition. However, it follows that the energy functional satisfies the Cerami (PS) condition.
