摘　　要：利用锥上的不动点定理,给出了非线性二阶三点边值问题解和正解的存在性定理.其中允许非线性项有一个负的下界.By using a fixed point theorem in cones,the existence of solutions and multiple solutions is considered for a nonlinear second-order three-point boundary value problem where nonlinear term is allowed to have a negative lower bound.

关 键 词：三点边值问题 半正非线性 不动点定理
