摘要
In this paper, we consider the following second-order three-point boundary value problem u"(t) + a(t)f(u(t)) = 0, 0 < t < 1, u(0) - u(1) = 0, u′(0) - u′(1) = u(1/2) where a : (0, 1) → [0, ∞) is symmetric on (0, 1) and may be singular at t = 0 and t = 1, f : [0, ∞) → [0, ∞) is continuous. By using Krasnoselskii's fixed point theorem in a cone, we get some existence results of positive solutions for the problem. The associated Green's function for the three-point boundary value problem is also given.
