Title：Revisiting Fourier series (Part II)

Abstract：This is a continuation of last week’s discussion on the theory of Fourier series. We will be mainly talking about trigonometric polynomials this time. The Weierstrass approximation theorem for trigonometric polynomials will be proved, with the main tool being periodic convolutions. At this stage, we basically follow Chapter 16 of Terence Tao’s book “Analysis II”.
