| Abstract: | In order to study nonlinear two-order three-point boundary value problem,this paper investigates the existence and multiplicity results of symmetric positive solutions by using the fixed point theorem and the monotone iterative technique.Not only was the existence of 2n(n is a natural number)symmetric positive solutions for the problems obtained,but also iterative schemes for approximating the solutions was established. |
