Abstract
§1. The Cardinal Function of Interpolation Theory is the functionwhich takes the values an at the points x = n. Ferrar has recently provedTheorem1. If are convergent, C(x)is an m-function3forThis means that C(x) is a solution of the intergral equationFerrar's proof deals with functions of a real variable and involves some rather difficult double limit considerations.
