本文用Monte Carlo方法计算了具有Z/sub 2/规范群的四维格点规范理论的路径积分。该系统表现出一级转变。这与近似的Migdal递归关系的含义相反，但与平均场理论的论点一致。我们的“数据”与低温膨胀和高温和低温相之间的确切二元性非常一致。
Using Monte Carlo techniques, we evaluate the path integral for the four-dimensional lattice gauge theory with a Z/sub 2/ gauge group. The system exhibits a first-order transition. This is contrary to the implications of the approximate Migdal recursion relations but consistant with mean-field-theory arguments. Our 'data' agree well with a low-temperature expansion and the exact duality between the high- and low-temperature phases.
