【Abstract】 In this paper,we are concerned with the following singular third-order nonlocal boundary value problem with integral boundary condition.Under various assumptions on nonhnear terms,we establish intervals of a parameter which yield the existence of at least one,two monotone positive solutions of the boundary value problem by applying the wellknown Guo-Krasnoselskii’s fixed point theorem.更多还原
