| Abstract: | 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 loeer bound. |
| Keywords: | three-point boundary value problem semipositone nonlineaxity fixed point theorem |
