ABSTRACT
Recent years, the fractional differential equations are increasingly used to describe optical and thermal system, controlling technique, robots, and other application fields. Especially, the existence of solutions of fractional differential equations which is abstracted from the practice gives a great help to solve the problems. This paper introduces the development of the fractional differential equations。 Then it discusses the proof of the existence of solutions by transforming fractional differential equations into equivalent integral equations, and it also proves the existence of solutions of nonlinear fractional diff
