| Abstract: | Using the method of upper and lower solutions, the existence of solutions of a second order three-point boundary value problem with mixed nonlinear boundary conditions was studied. We used a different modification of the nonlinearity f and obtained some sufficient criterion of existence with solutions. The result improved and extended some known results. |
