  The relation of confinement scenarios based on topological configurations and
the Gribov-Zwanziger scenario is examined. To this end the eigenspectrum of the
central operator in the Gribov-Zwanziger scenario, the Faddeev-Popov operator,
is studied in topological field configurations. It is found that instantons,
monopoles, and vortices contribute to the spectrum in a qualitatively similar
way. Especially, all give rise to additional zero-modes and thus can contribute
to the Gribov-Zwanziger confinement mechanism. Hence a close relation between
these confinement scenarios likely exists.
