Abstract
We prove the existence of classical positive radial solutions to the boundary value problems
where \(b>0\), \(B(b)=\{x\in \mathbb {R}^N:|x|<b\}\), \(a:[0, b]\rightarrow \mathbb {R}\) is a continuous function which may change sign, \(f:[0,\infty )\rightarrow \mathbb {R}\) is a continuous function with \(f(s)>0\) in [0, b], and \(\lambda >0\) is sufficiently small. Our approach is based on the Leray–Schauder fixed point theorem.
