| Abstract: | The integral boundary value problems of nonlinear delay functional differential equations with left and right Riemann-Liouville fractional derivatives were studied by using the method of lower and upper solutions. Some new results on the existence and uniqueness of solutions were established by using the method of upper and lower solutions, iteration method for solving differential equations and the error estimations were presented. Finally, an example was given out to illustrate the wide applicability of the results and methods. |
