A weaker condition for the stability of nonsymmetric CNN's

In this paper, a new sufficient condition is given for the stability of a nonsymmetric CNN. This condition is less strict than that was given in Savaci and Vandewalle (1993). It also assures a stronger stability property than that was given in Chua and Roska (1990) as the existence of a stable equilibrium point is guaranteed. Therefore this condition allows more CNN types to be included into the class of stable CNN's.<>
