Exponential stability of nonlinear impulsive neutral integro-differential equations Original Research Article

In this paper, a nonlinear impulsive neutral integro-differential equation with time-varying delays is considered. By establishing a singular impulsive delay integro-differential inequality and transforming the nn-dimensional impulsive neutral integro-differential equation to a 2n2n-dimensional singular impulsive delay integro-differential equation, some sufficient conditions ensuring the global exponential stability in PC1PC1 of the zero solution of an impulsive neutral integro-differential equation are obtained. The results extend and improve the earlier publications. An example is also discussed to illustrate the efficiency of the obtained results.
