Renormalization: An Introduction By Manfred Salmhofer
Publisher: Spr.ing.er 1999 | 241 Pages | ISBN: 3540646663 | DJVU | 1 MB




This monograph is the first to present the recently discovered renormalization techniques for the Schrdinger and Dirac equations, providing a mathematically rigorous, yet simple and clear introduction to the subject. It develops field-theoretic techniques such as Feynman graph expansions and renormalization, taking pains to make all proofs as simple as possible by using generating function techniques throughout. Renormalization is performed by using an exact renormalization group differential equation, a technique that provides simple but complete proofs of the theorems.
