22: 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.
…
►For example, positive real values of with comprise stable pairs, as do values of and that correspond to real, but noninteger, values of .
…
►Also, all nontrivial solutions of (28.2.1) are unbounded on .
►For real
and
the stable regions are the open regions indicated in color in Figure 28.17.1.

…
►For example, if is real, then the zeros of are all complex unless for some positive integer , in which event has two real zeros.
►The distribution of the zeros of in the sector in the cases is obtained on rotating Figures 10.21.2, 10.21.4, 10.21.6, respectively, through an angle so that in each case the cut lies along the positive imaginary axis.

For the number of zeros of in the sector , when is real, see Watson (1944, pp. 511–513).
