Comments on "Absolute exponential stability of a class of neural networks with unbounded delay".
Recently, Zhang, Suda and Iwasa [Zhang, Jiye, Suda, Yoshihiro, & Iwasa, Takashi (2004). Absolute exponential stability of a class of neural networks with unbounded delay, Neural Network, 17, 391-397] established the following: In this letter, we would like to point out that the necessary condition in above Result given by Zhang et al. (2004) is incorrect in general.
