设B是有限CW复形,G是紧连通李群。我们证明了对于n<∞,B上的主G丛的规范群的个数是有限的,直到等价。作为例子,我们给出了S4上主SU(2)-丛的规范群的单等价类型个数的下界。
LetBbe a finite CW complex andGbe a compact connected Lie group. We show that the number of gauge groups of principalG‐bundles overBis finite up toAn‐equivalence forn<∞. As an example, we give a lower bound of the number ofAn‐equivalence types of gauge groups of principal SU(2)‐bundles overS4.
