本文开始提出用变分办法来研究四维格点规范理论。首先通过分析较简单的SU(2)手征模型来演示变分的方法,然后对SU(2)格点规范理论中的混合基础——伴随表示作用量模型作了系统的研究,结果比标准的平均埸结果有改进。早先在平均埸的计算中
This paper begins to propose a variational approach to the study of four-dimensional grid point theory. Firstly, the simpler SU(2) chiral model was used to demonstrate the variational method. Then the mixed basis of the SU(2) grid specification theory was studied systematically. The results were compared with the standard. The average results have improved. Earlier in the calculation of average 埸
