Wilson loop expectation in 4D $$\mathbb {Z}_2$$ Z 2 lattice gauge theory is computed to leading order in the weak coupling regime. This is the first example of a rigorous theoretical calculation of Wilson loop expectation in the weak coupling regime of a 4D lattice gauge theory. All prior results are either inequalities or strong coupling expansions.

伊辛格规范理论中的威尔逊环

4D $$\mathbb {Z}_2$$ Z 2 格子规范理论中的威尔逊环期望被计算为弱耦合机制中的领先阶。这是在 4D 晶格规范理论的弱耦合机制中对威尔逊环期望进行严格理论计算的第一个例子。所有先前的结果要么是不等式，要么是强耦合扩展。
