摘要：We give a short review of recently obtained results on a new lattice formulation of the non-linear
change of variables which was once called the Cho–Faddeev–Niemi decomposition in SU(2)
Yang-Mills theory. Based on this formulation, we proposed a new gauge-invariant definition
of the magnetic monopole current which guarantees the magnetic charge quantization. We also
demonstrated the magneticmonopole dominance in the string tension in SU(2) Yang-Mills theory
on a lattice. Our formulation enables one to reproduce in the gauge-invariant way remarkable
results obtained so far only in the Maximally Abelian gauge.
