Abstract

This paper concerns the existence and multiplicity of positive solutions for a class of nonresonant m-point boundary-value problem of second-order differential equations Lx = λw(t)ƒ(t, x), 0 < t < 1. The interesting points are that Lx ≔ –x″ + ρqx and w is Lp-integrable for some 1 ≤ p ≤ +∞. The arguments are based upon fixed point theorems in a cone and Hölder's inequality. The nonexistence of positive solution is also studied. In addition, some examples are included to demonstrate the main results.
