The Luttinger model was introduced to illustrate the theory of Tomonaga viaan exactly soluble model. It became soon the subject of great interest also onthe part of Mathematical Physics and a key to the investigations of themathematical properties of Condensed Matter Physics. This paper reviews aspectsof the above developments relevant for renormalization group methods.Comment: Plain Te
