Squire’s transformation

The change of variables (12-310) is a version of Squire s transformation, in recognition of Squire who first discovered it. 

The transformed problem (12 311) is mathematically equivalent to the special case of a 2D disturbance with a = v = 0. Inherent in Squire s transformation is the fact that, for... 

The Equations (12-321) are an obvious generalization of the inviscid, linearized disturbance equations (12-307), and it is therefore not surprising that Squire s theorem turns out to be applicable. To see this, we apply Squire s transformation (12-310), plus the one additional condition...
