Asymptotic behavior of minimal solutions of $-\Delta u=\lambda f(u)$ as $\lambda\to-\infty$.

We consider the Dirichlet problem $-\Delta u=\lambda f(u)$ with $\lambda<0$ and $f$ non-negative and non-decreasing. We show existence and uniqueness of solutions $u_\lambda$ for any $\lambda$ and discuss their asymptotic behavior as $\lambda\to-\infty$. In the expansion of $u_\lambda$ large solutions naturally appear.
