摘要：We investigate the non-Abelian Bianchi identities in pure SU(2) lattice Yang-Mills theory in three
and four dimensions. The non-Abelian Stokes theorem proposed recently allows to formulate the
Bianchi identities in terms of local physical fluxes. Then the violation of Bianchi identities becomes
a well defined concept ultimately related to chromomagnetic fields degeneracy points.
We present numerical evidences that in D=4 the suppression of the Bianchi identities violation
destroys confinement while the removal of the degeneracy points drives the theory to the topologically
non-trivial sector.
