Strong maximum principle for a sublinear elliptic problem at resonance
We examine the semilinear resonant problem $$ -\Delta u = \lambda_1 u + \lambda g(u) \quad \text{in } \Omega,\ u\geq 0 \text{ in } \Omega, \ u_{|\partial\Omega}=0, $$ where $\Omega\subset\mathbb R^N$ is a smooth, bounded domain, $\lambda_1$ is the first eigenvalue of $-\Delta$ in $\Omega$, $\lam...
