我们用新的晶格变量给出了晶格SU(N)Yang-Mills理论的新描述。我们以前的工作已经在SU(2)Yang-Mills理论中从定义和提取拓扑自由度的角度证明了这种描述的正确性，例如在夸克禁闭中起主导作用的规范不变磁单极子和涡旋。特别地，我们发现SU(3)格子Yang-Mills理论有两种可能的选择，最大选择和最小选择：最小选择的存在一直被忽略，而最大选择重现了传统的SU(3)Cho-Faddeev-Niemi-Shabanov分解。这一新的描述为理解基于双重超导的夸克禁闭机制提供了重要的框架。
We give new descriptions of lattice SU(N) Yang–Mills theory in terms of new lattice variables. The validity of such descriptions has already been demonstrated in the SU(2) Yang–Mills theory by our previous works from the viewpoint of defining and extracting topological degrees of freedom such as gauge-invariant magnetic monopoles and vortices which play the dominant role in quark confinement. In particular, we have found that the SU(3) lattice Yang–Mills theory has two possible options, maximal and minimal: The existence of the minimal option has been overlooked so far, while the maximal option reproduces the conventional SU(3) Cho–Faddeev–Niemi–Shabanov decomposition in the naive continuum limit. The new description gives an important framework for understanding the mechanism of quark confinement based on the dual superconductivity.
