What is it about?

After establishing a comparison result , apply the monotone iterative technique and lower-upper solution method, we obtain the existence of extremal solutions for a fractional q-difference equation with integral boundary conditions. A comparison theorem under weak conditions is also build, we can construct two iterative schemes approximating the extremal solutions.

Why is it important?

We give some new sufficient conditions under such fractional q-difference problem have extremal solutions, Our finding show that the existence of solutions need the corresponding comparison theorem for fractional q-difference inequalities. two iterative schemes approximating the extremal solutions are constructed.
