Abstract: By using the fixed point theorem on expansion and compression of cones, we study the existence of positive solutions for a class of periodic boundary value problems of third-order ordinary differential equations. The results show that there exists at least one positive solution to the above problem when the nonlinear term f satisfies appropriate conditions.
Key words: third-order differential equation, periodic boundary value, Green function, positive solution
