In lattice gluodynamics in the maximal Abelian projection, SU(2) --> U
(1), the dynamics is governed by diagonal gluons. In the minimal proje
ction, it is instead governed by off-diagonal gluons. In the maximal A
belian projection, color confinement is thus due to a condensate of U(
1) monopoles, while in the minimal Abelian projection the dynamics of
the system is driven by vector Goldstone fields and topological defect
s constructed from them.
