Abstract

In this paper, the global exponential stability and periodicity are investi-gated for impulsive neural network models with Lipschitz continuous activation func-tions and piecewise alternately advanced and retarded argument of generalized argu-ment (in short IDEPCAG). The sufficient conditions for the existence and uniqueness of periodic solutions of the model are established by applying fixed point theorem and the successive approximations method. By constructing suitable differential in-equalities with piecewise alternately advanced and retarded argument, some sufficient conditions for the global exponential stability of the model are obtained. Typical numerical examples with simulations are utilized to illustrate the validity and im-provement in less conservatism of the theoretical results.
