| Abstract: | In this paper, we study the third-order triple-point nonlinear boundary value problems with sign changing nonlinearities by employing Krasnoselkii-Guo fixed point theorem and Avery-Henderson fixed point theorem,and establish results on the existence of at least one or two positive solutions to the boundary value problems. |
