Existence of triple positive solutions for a third-order three-point boundary value problem

Abstract: In this paper we investigate the existence of triple positive solutions for the nonlinear third-order three-point boundary value problemwhere δ ∈ (0, 1), η ∈ [1/2, 1) are constants. f : [0, 1] × [0, ∞) × R 2 → [0, ∞), q : (0, 1) → [0, ∞) are continuous. First, Green's function for the associated linear boundary value problem is constructed, and then, by using a fixed-point theorem due to Avery and Peterson, we establish results on the existence of triple positive solutions to the boundary value problem.

“…We quote also the reasearchs of [2,4,5,6,7,8,12,13,14,15,16,18,20] which concern the differential equations under various boundary conditions and by different approaches. Motivated by the works mentioned above, we obtain the existence results for the problem (1.1)-(1.2) by using the Leray-Shauder fixed point theorem if f 0 = 0 ( condition f ∞ = ∞ being unnecessary ) , as well as, for f ∞ = 0 ( condition f 0 = ∞ being unnecessary ).…”
