On the Computation of Fourier Coefficients
"... In this paper we derive an identity for the Fourier coefficients of a differentiable function f(t) in terms of the Fourier coefficients of its derivative f ′ (t). This yields an algorithm to compute the Fourier coefficients of f(t) whenever the Fourier coefficients of f ′ (t) are known, and vice ver ..."

AN UPDATE ALGORITHM FOR FOURIER COEFFICIENTS
"... In this article we present a new technique to obtain the Discrete Fourier coefficients for a moving data window of an arbitrary length. Unlike the classic approaches we derive an update algorithm by exploiting results of update formulas for orthogonal polynomials. For the vector space of polynomial ..."

Quadrature formulae for Fourier coefficients
, 2009
"... We consider quadrature formulas of high degree of precision for the computation of the Fourier coefficients in expansions of functions with respect to a system of orthogonal polynomials. In particular, we show the uniqueness of a multiple node formula for the FourierTchebycheff coefficients given b ..."

FOURIER COEFFICIENTS OF HECKE EIGENFORMS
"... Abstract We provide systematic evaluations, in terms of binary quadratic representations of 4p, for the pth Fourier coefficients of each member f of an infinite class C of CM eigenforms. As an application, previously conjectured evaluations of three algebrogeometric character sums can now be form ..."

Fourier Coefficients for G_2

"... this paper, we develop a theory of Fourier coefficients c A (f) for certain modular forms f on the split group G 2 over Q. The coefficients are indexed by totally real cubic rings A: commutative rings with unit that are free of rank 3 over Z, such that the Ralgebra ..."

On signs of Fourier coefficients of cusp forms

"... We consider two problems concerning signs of Fourier coefficients of classical modular forms, or equivalently Hecke eigenvalues: first, we give an upper bound for the size of the first signchange of Hecke eigenvalues in terms of conductor and weight; second, we investigate to what extent the signs ..."
