This paper discusses the existence of solutions to antiperiodic boundary
value problem for nonlinear impulsive fractional differential equations. By using Banach fixed point theorem, Schaefer fixed point theorem, and nonlinear alternative of Leray-Schauder type theorem, some existence results of solutions are obtained.
An example is given to illustrate the main result.
