WebUrysohn’s lemma implies the density of Co(T) in L2(T), so we have the completeness of Fourier series in L 2(T). Thus, Fourier series of L(T) functions converge to them in the L2(T) topology. A. Zygmund’s Trigonometric Series, I, II contains much more bibliographic and historical information. 1. Pointwise convergence WebThis series is called the trigonometric Fourier series, or simply the Fourier series, of f (t). The a’s and b’s are called the Fourier coefficients and depend, of course, on f (t). The coefficients may be determined rather easily by the …
