Attracting and quasi-invariant sets of non-autonomous neural networks with delays

In this paper, a class of non-autonomous neural networks with delays is considered. By using the properties of spectral radius of nonnegative matrix, two new integral inequalities are established. Based on the integral inequalities, some new sufficient conditions for the existence of quasi-invariant and attracting sets of the non-autonomous neural networks with delays are obtained. The framework of the tions. One example is presented to illustrate the effectiveness of our conclusion. & 2011 Elsevier B.V. All rights reserved.
