The uniqueness of positive solution for a singular fractional differential system involving derivatives

By using the fixed point theorem of the mixed monotone operator, the uniqueness of positive solution for a singular fractional differential system involving derivatives is established. An example is then given to illuminate the application of the main results.

► Fractional modeling dynamics systems are studied. ► Existence and uniqueness of positive solutions are presented. ► The fractional differential systems have higher singularity. ► The mixed monotone operator is used.
