"From the beginning of the history of cinema to the present day, from Lubitsch to Jeunet, Montmartre has always been a favoured setting for films by French and foreign directors alike. Montmartre, with its charm and history, embodies the very image of Paris, and has become an actor in its own right in films. 'Montmartre: A Film Set' evokes the various preferred locations for these films in Montmartre (the Moulin Rouge, Place Pigalle, Barbès, Sacré-Cœur, and so on), its atypical scenes (the stairways, lanes, small houses, and lamp posts), and its residents (the artistes, dancers, ordinary people, cops, thugs, and prostitutes). The Paris of parties and pleasure, as well as that of crime and perdition, often represented by the districts of La Chapelle, Pigalle, and La Goutte d'Or, has been integral to the celebration of art and poetry on the Butte Montmartre."-- Back cover

Focusing on the purely theoretical aspects of strongly correlated electrons, this volume brings together a variety of approaches to models of the Hubbard type - i.e., problems where both localized and delocalized elements are present in low dimensions. The chapters are arranged in three parts. The first part deals with two of the most widely used numerical methods in strongly correlated electrons, the density matrix renormalization group and the quantum Monte Carlo method. The second part covers Lagrangian, Functional Integral, Renormalization Group, Conformal, and Bosonization methods that can be applied to one-dimensional or weakly coupled chains. The third part considers functional derivatives, mean-field, self-consistent methods, slave-bosons, and extensions.
