Abstract
Abstract Given a subset A of the natural numbers = {0, 1, 2, ···} (resp. of the ring / N of residue classes modulo a positive integer N), we introduce certain sums of roots of unity associated with A. We study some of their properties, and we use them to obtain new expressions for the classical functions that characterize A, i.e. of the representation function, the counting function and the characteristic function of A. We also give an example of computations of the representation function using such expressions.
