我们提出了几种无费密子格点规范理论的新作用量形式,证明了它们符合Wilson对格点作用量提出的条件,讨论了它们与几种常用的作用量间的关系。并推导了在使用新作用量时Wilson圈满足的Schwinger-Dyson方程,证实了当N→∞时,E-K模型中的Schwinger-Dyson方程和标准格点模型相同。In lattice gauge theory some alternative actions without fermions were proposed, which obey Wilson's conditions for lattice action and were related with usually adopted actions. The Schwinger-Dyson equation obeyed by Wilson loop amplitude with the alternative actions was derivated. We verified that, in large N limit in E-K reduced model, the same Schwinger-Dyson equation exists as in the standard model.
