Abstract (EN): We review developments concerning the effect of correlations on the elec- tronic properties of one-dimensional systems, focusing our analysis on the one- dimensional Hubbard model. We consider methods used to describe the ex- otic properties of these systems, ranging from bosonization associated with the Tomonaga and Luttinger liquid behavior, to the Bethe ansatz solution, referring to all energy scales of solvable quantum problems and the pseudoparticle de- scription. We use that description to study the model energy spectrum and the low-energy quantities. In the ensuing companion chapter we discuss the relation of the electronic operators to these quantum objects.
