A Renormalization Procedure for the Hubbard Model

The properties of the many-body systems have been an amazing question from Newton to the present time. In solid state physics, too, even if a large amount of these models have been solved and analysed, the behaviour of great variety of microscopical models remains not understood. This short review is devoted to one of these many-body systems, the Hubbard model, wich is thought to be appropiate to describe phenomena ranging from the itinerant ferromagnetism to the High-T c superconductivity .
