One can proceed by first using the Littlewood-Paley inequality to estimate the L^r norm of pi_lh(f,g) by the L^r norm of the square function of the summands pi_lh(f, psi_j(D) psi_j(D) g), at which point … WebMar 24, 2024 · A Fourier series is an expansion of a periodic function f(x) in terms of an infinite sum of sines and cosines. Fourier series make use of the orthogonality relationships of the sine and cosine functions. The computation and study of Fourier series is known as harmonic analysis and is extremely useful as a way to break up an arbitrary periodic …
