Renormalization: An Introduction

Why another book on the renormalization of field theory? This book aims to contribute to the bridging of the gap between the treatments of renor­ malization in physics courses and the mathematically rigorous approach. It provides a simple but rigorous introduction to perturbative renormalization, and, in doing so, also equips the reader with some basic techniques which are a prerequisite for studying renormalization nonperturbatively. Beside these technical issues, it also contains a proof ...
