Abstract
In this paper, by using the fixed points of strict-set-contractions, we study the existence of at least one or two positive solutions to the four-point boundary value problem y"(t)+a(t)f(y(t))=θ, 0＜t＜1, y'(0)=μ y'(ξ), y(1)=β y(η), in Banach space E, where θ is zero element of E, 0＜ξ, η＜1, 0＜μ＜1 and 0＜β＜1. As an application, we also give one example to demonstrate our results.关键词
