Abstract
In this work, the concept of fractional calculus on time scales is developed to the study of fractional differential equations on time scales. By using the Banach contraction principle and the Schauder fixed-point theorem, some existence results for fractional differential equations on time scales are obtained. Finally, an example is given to illustrate the main results.
