Existence of Solutions of Boundary Value Problems for a Class of Third Order Nonlinear Differential Equations

The upper and lower solution method is used to discuss the existence of solutions of three-point boundary value problare for the third order nonlinear differential equation satisfying the following linear boundary conditions and where. Asa generalization of the results given by Zhao Weili et al. Corresponding theorems for the following nonlinear boundary conditions are also given.
