Abstract :
This letter points out that a Liapunov function used by the present authors in an earlier publication on absolute and structural stability of neural circuits easily proves a stronger version of the sufficient part of the result contained in the paper by Forti, Manetti and Marini (1994) as well as in a subsequent publication. Comments are made on the set of interconnection matrices that determine necessary and sufficient conditions for absolute stability of the class of neural circuits considered and as a consequence a conjecture is formulated.<>
