A comment on "Comments on 'Necessary and sufficient condition for absolute stability of neural networks'"
Sabri Arik, V. Tavşanoglu · IEEE Transactions on Circuits and Systems I Fundamental Theory and Applications · 1998
This letter points out that a new majorization of the derivative of the Lyapunov function used in the above letter [see ibid., vol.42, p.497-9, 1995] gives a new, weaker condition on the interconnection matrix that is sufficient for the global asymptotic stability (GAS) of the equilibrium point for dynamical neural networks. The result also includes some earlier results derived in the literature.
