XVIII.—The Definite Integrals of Interpolation Theory
Published online by Cambridge University Press: 15 September 2014
Extract
It is well known that, if the infinite series
is convergent for any non-integral value of z, it is uniformly convergent in any finite region of the z-plane and represents an integral function C(z), say, such that C(n) = an for n = 0, ± 1, ± 2, … It is called the Cardinal Function of the table of values, and is identical with Gauss's Interpolation Formula (suitably bracketed).
The function C(z) defined by the series (1) has been given two different definite integral representations, due to Ferrar and Ogura respectively.
