Integral equation method for effecting Kinnersley-Chitre transformations. II

Abstract
Our previously presented integral equation formulation of the Kinnersley-Chitre transformation theory is generalized to the case of electrovac-to-electrovac transformations. The solution of the integral equation for a case in which the kernel has a finite number of simple poles is obtained. In particular, we show that when the transformation corresponding to one simple pole is applied to Minkowski space, one obtains the Ehlers transform of the extreme charged Kerr-NUT (Newman-Unti-Tambourino) space. We also find the general solution corresponding to a confluence of two simple poles.
