“…As well known, in practice time-delays are often encountered in various engineering, biological, and economic systems. Up to now, the stability analysis problem of neural networks with time delay has attracted a large amount of research interest and many sufficient conditions have been proposed to guarantee the asymptotic or exponential stability for the neural networks with various types of time delays such as constant, time-varying, or distributed, see for example, [1,2,10,[12][13][14][15]17,21,24,25,28] and the references therein.…”
