We may consider the algebra of those functions f where the majorants of the Fourier coefficients an are summable. In other words Example
We may consider a weight function w on Z such that in which case A w = { f : f = ∑ n a n e i n t , ‖ f ‖ w = ∑ n | a n | w < ∞ } is a unitary commutative Banach algebra. These alg
