### Abstract

In this paper we shall consider the nonresonance Dirichlet boundary value problem $$\left\{ {\begin{array}{*{20}l} {{ - {x}\ifmmode{''}\else''\fi + pp{\left( t \right)}x = \lambda f{\left( {t,x} \right)},} \hfill} & {{t \in {\left( {0,1} \right)},} \hfill} \\ {{x{\left( 0 \right)} = x{\left( 1 \right)} = 0,} \hfill} & {{} \hfill} \\ \end{array} } \right.$$ where λ>0 is a parameter, p>0 is a constant. Intervals of λ are determined to ensure the existence of a nonnegative solution of the boundary value problem. For λ=1, we shall also offer criteria for the existence of eigenfunctions. The main results include and improve on those of [2,4,6,8].
