In the border country between complex analysis, harmonic analysis and differential equations, there can be found many popular transforms, of which those of Fourier and Laplace are probably the most commonly used. This book is concerned with another one, which is more rarely sighted.
The Cauchy transform of a finite complex measure µ defined on the unit circle
in the complex plane is the analytic function Kµ defined by

. Its name derives from the observation that Cauchy's integral formula, when applied to an analytic function f, is equivalent to the statement that the Cauchy transform of the measure
