摘要This paper deals with the global convergence and stability of the Hopfield-type neural networks under the critical condition that M-1 (Gamma) = L-1 D Gamma - (Gamma W + W(T)Gamma) / (2) is nonnegative for any diagonal matrix Gamma, where W is the eight matrix of the network, L = diag {L-1, L-2,..., L-N} with L-i being the Lipschitz constant of g(i) and G(u) = (g(1)(u(1)),g(2)(u(2)),...g(N)(u(N)))(T) is the activation mapping of the network. Many stability results have been obtained for the Hopfield-type neural networks in the noncritical case that M-1 (Gamma) is positive definite -for some positive definite diagonal matrix F. However, very few results are available on the global convergence and stability of the networks in the critical case. In this paper, by exploring two intrinsic features of the activation mapping, two generic global convergence results are established in the critical case for the Hopfield-type neural networks, which extend most of the previously known globally asymptotic stability criteria to the critical case. The results obtained discriminate the critical dynamics of the networks, and can be applied directly to a group of Hopfield-type neural network models. An example has also been presented to demonstrate both theoretical importance and practical significance of the critical results obtained.
