Resonance problems for the \(p\)-Laplacian. (English) Zbl 0940.35087

Using variational arguments the authors prove the existence of a weak solution for the boundary value problem \[ \begin{cases} -\Delta_p u-\lambda|u|^{p-2}u+f(x,u)=0\quad&\text{in }\Omega,\\ u=0\quad&\text{on }\partial\Omega,\end{cases} \] where \(\Delta_p u=\)div\((|Du|^{p-2}Du)\), \(p>1\), \(\Omega\) is a bounded domain of \(\mathbb R^N\), \(\lambda\in\mathbb R\) and \(f:\Omega\times\mathbb R \to \mathbb R\) is a bounded Carathéodory function such that there exist \(\lim_{t\to\pm\infty}f(x,t)= f^\pm(x)\) a.e. in \(\Omega\), with either \[ \begin{gathered}\int_{v>0}f^+ v+\int_{v<0}f^- v>0, \qquad\text{or} \tag{(LL)}\(_\lambda^+\)\\ \int_{v>0}f^+ v+\int_{v<0}f^- v<0\phantom{\qquad\text{or}} \tag{(LL)}\(_\lambda^-\)\end{gathered} \] for all \(v\in\)Ker\((-\Delta_p-\lambda)\setminus\{0\}\), and also there is \(g\in L^{p/(p-1)}(\Omega)\) such that \[ |f(x,t)|\leq g(x)\quad\text{in }\Omega\times\mathbb R. \]
The conditions (LL)\(_\lambda^\pm\) are the standard Landesman – Laser conditions for resonance problems, and of course are trivially satisfied whenever \(\lambda\) is not an eigenvalue.
