Abstract

In this article, we give a formula for the generalization of the binomial coefficient to the complex numbers as a linear combination of \sinc functions. We then give a general formula to compute the integral on the real line of the product of the binomial coefficient and a given function, which, in some cases, turns out to be equal to the series of their values on the integers. Finally, we establish a list of identities obtained by applying these formulas.
