本文分析了规范群上同调的拓扑障碍。指出规范群上同调的上边缘算子相当于?ech的差映射算子。采用逐级分区的方法克服以往常用的d-1算子的含混性,而且将各阶上闭链与指数Z相联系,澄清了规范群上闭链的整体拓扑意义。In this paper we analyze the topological obstruction in gauge group cohomology. By means of ?ech-de Rham double complex, we have used the region subdivision method to go over each order obstructions of operation d-1, and each order cocycle is connected with the index Z, so the global topological meaning of cocycle for gauge group has been-clarified.
