   Fang Zhang  Feng Wang  Fuli Wang《Annals of Differential Equations》,2011年第2期
   The existence and multiplicity of positive solutions to a periodic boundary value problem for nonlinear third-order ordinary differential equation are established, based on the zero point theorem concerning cone expansion and compression of order type.
