… ►Figure 4.15.7 illustrates the conformal mapping of the strip onto the whole -plane cut along the real axis from to and to , where and (principal value). …Lines parallel to the real axis in the -plane map onto ellipses in the -plane with foci at , and lines parallel to the imaginary axis in the -plane map onto rectangular hyperbolas confocal with the ellipses. In the labeling of corresponding points is a real parameter that can lie anywhere in the interval . … ► …13: 13.16 Integral Representations

►As described in §3.7(ii), to ensure stability the integration path must be chosen in such a way that as we proceed along it the wanted solution grows at least as fast as all other solutions of the differential equation.
In the case of , for example, this means that in the sectors we may integrate along outward rays from the origin with initial values obtained from §9.2(ii).

►Among the integral representations of the Airy functions the Stieltjes transform (9.10.18) furnishes a way of computing in the complex plane, once values of this function can be generated on the positive real axis.
