A comment on comments on \u27necessary and sufficient condition for absolute stability of neural networks\u27

This letter points out that a statement in the above letter, 1 saying that the sufficiency part of absolute stability result on neural networks in the above letter1 (Theorem 2.1) includes the sufficiency part of the absolute stability result in Forti et al. [1], is not correct under the stated conditions. On the other hand, it is shown that the sufficiency part of absolute stability result in Forti et al. [1] is included by the sufficiency part of a conjecture stated in the above letter1 (Conjecture 3.3). © 1998 IEEE
