Sufficient conditions for all solutions of the neutral differential equations of the form d/dt (x(t) + c(t)x(t-tau)) + p(t)x(t) + q(t)x(t-sigma) = 0 to approach sere as t --> infinity are established. Some applications to neutral logistic equations and neural networks of neutral type are also presented. (C) 2000 Elsevier Science Ltd. All rights reserved.
