Upper and lower solution method for a fourth-order four-point boundary value problem on time scales. (English) Zbl 1361.34103

Summary: We consider a fourth-order four-point boundary value problem on time scales. We establish criteria for the existence of a solution by developing the upper and lower solution method and the monotone iterative technique.
