Many evolutionary processes, particularly some biological systems, exhibit
impulsive dynamical behaviors, which can be well described by impulsive Hop
field neural networks. This paper formulates and studies a model of delayed
impulsive Hopfield neural networks. Several fundamental issues such as glo
bal exponential stability, existence and uniqueness of the equilibrium of s
uch networks are established. A numerical example is given for illustration
and interpretation of the theoretical results. (C) 1999 Elsevier Science L
