A First Course in Harmonic Analysis

This book is intended as a primer in harmonic analysis at the un­ dergraduate level. All the central concepts of harmonic analysis are introduced without too much technical overload. For example, the book is based entirely on the Riemann integral instead of the more demanding Lebesgue integral. Furthermore, all topological questions are dealt with purely in the context of metric spaces. It is quite sur­ prising that this works. Indeed, it turns out that the central concepts theory can be explain
