Global exponential stability of impulsive integro-differential equation

In this paper, an impulsive integro-differential equation is considered. By establishing an integro-differential inequality with impulsive initial conditions and using the properties of M-cone and eigenspace of the spectral radius of nonnegative matrices, some new sufficient conditions for global exponential stability of impulsive integro-differential equation are obtained. The results extend and improve the earlier publications. An example is given to demonstrate the effectiveness of the theory.
