| Abstract: | The employment of supersolution and subsolution,the definition of fixed cone and the application of the fixed point theorem of cone mapping result in some methods to the existence of positive solutions to second order multipoint boundary value,and generalize the results of positive solution for second-order three-point boundary value problem in relative literature. |
