By using the method of monotone iterative technique together with upper and lower solutions, conditions for the existence and approximation of minimal and maximal solutions to the BVP under consideration are constructed. Some adequate results for different kinds of Ulam stability are investigated. Maximum error estimates for the corresponding solutions are given as well. Two examples are provided to illustrate the results.eninfo:eu-repo/semantics/closedAccessFractional Differential EquationsMonotone Iterative TechniqueUlam StabilityUpper and Lower Solutions Extremal SolutionsOn stable iterative solutions for a class of boundary value problem of nonlinear fractional order differential equationsOn Stable Iterative Solutions for a Class of Boundary Value Problem of Nonlinear Fractional Order Differential EquationsArticle42396998110.1002/mma.5407
