Elements of Fourier Analysis
The Stone-Weierstrass theorem is concerned about approximation of continuous functions by polynomials. In this chapter,1 we discuss yet another type of approximation which applies to functions that are not necessarily continuous. The applications of the kind of approximation we are going to study here are of considerable importance especially in physics and engineering.
