Abstract :
Results are obtained by the construction of a quadratic form of Lyapunov function, following the method of McGee and MacLellan. A comparison with Fallside and Ezeilo shows that, for certain systems containing a nonlinearity which is a function of several variables, previously established sufficient conditions for stability are substantially weakened.
