摘要
We establish existence results of the following three-point boundary value problems: u ''(t) + f(t, u(t)) = 0, t is an element of (0, 1), (BC)u(0) = 0 and u(1) = delta u(eta), where 0 < eta < 1 and 0 < delta <= 1. The approach applied in this paper is upper and lower solution method associated with basic degree theory or Schauder's fixed point theorem. We deal with this problem with the function f which is Caratheodory or singular on its domain.
