We prove uniqueness of positive solutions for the boundary value problem\begin{equation*}\left\{\begin{array}{l}-\Delta u=\lambda f(u)\text{ in }\Omega , \\\ \ \ \ \ \ \ u=0\text{ on }\partial \Omega ,\end{array}\right.\end{equation*}where Ω is a bounded domain in $\mathbb{R}$n with smooth boundary ∂ Ω, λ is a large positive parameter, f:(0,∞) → [0,∞) is nonincreasing for large t and is allowed to be singular at 0.
