    Title: An introduction to the Gribov problem and its consequences
    Abstract: In 1978, Gribov and Singer showed that the gauge-fixing procedure is not complete in non-Abelian gauge theories. In particular, after choosing a gauge condition, field configurations compatible with such a condition and related via gauge transformations exist (Gribov copies). In order to improve the standard Faddeev-Popov method, Gribov and Zwanziger developed a systematic way to deal with those copies in the Landau gauge giving rise to the so-called Gribov-Zwanziger action. In this talk, I will review this construction and comment on some recent developments focusing on pure Yang-Mills theories emphasizing the achievements as well as the challenges of this approach.
