标题： Mean distribution approach to spin and gauge theories

摘要： 我们为自旋模型中链接的分布以及规范理论中面片的分布制定了自洽方程。 这改进了已知的平均场、平均链路和平均面片近似方法，使得我们可以自洽地确定所考虑变量的所有矩，而不仅仅是第一个。 我们在阿贝尔和非阿贝尔情况下都给出了例子。 显示英文摘要

摘要： We formulate self-consistency equations for the distribution of links in spin models and of plaquettes in gauge theories. This improves upon known mean-field, mean-link, and mean-plaquette approximations in such that we self-consistently determine all moments of the considered variable instead of just the first. We give examples in both Abelian and non-Abelian cases.
