Abstract:

We investigated a system of nonlinear fractional differential equations subjecting to multipoint boundary conditions, and figured out the Green’s function. Using the increase operator fixed point theorem and the monotone iteration technique, we obtained the existence of positive solutions and established successively the iterative sequences of approximating solutions.

Key words: fractional differential equation, positive solution, approximating solution, iterative sequence
