§28.17 Stability as
►If all solutions of (28.2.1) are bounded when along the real axis, then the corresponding pair of parameters is called stable. All other pairs are unstable. ►For example, positive real values of with comprise stable pairs, as do values of and that correspond to real, but noninteger, values of . ►However, if , then always comprises an unstable pair. …19: 10.75 Tables
