Abstract:

On the basis of a coupled fixed point theorem on ordered metric spaces, we studied the existence and uniqueness of a positive solution for a kind of singular nonlinear fractional differential system of equations boundary value problem and obtained 2 theorems the existence and uniqueness  of solutions of such equations.

Key words: singular fractional differential system of equations; positive solution, ordered metric space, coupled fixed point
