规范群的$A_n$ -等价型的直接性

Finiteness of $A_n$-equivalence types of gauge groups

Mitsunobu Tsutaya

摘要:

设$B$是有限CW复形,$G$是紧连通李群.证明了$B$上主$G$ -丛的规范群的个数是有限的,直到$n<\infty$的$A_n$ -等价.作为例子,我们给出了$S^4$上主$\SU(2)$ -丛的规范群的$A_n$ -等价型个数的一个下界.

英文摘要:

Let $B$ be a finite CW complex and $G$ a compact connected Lie group. We show that the number of gauge groups of principal $G$-bundles over $B$ is finite up to $A_n$-equivalence for $n<\infty$. As an example, we give a lower bound of the number of $A_n$-equivalence types of gauge groups of principal $\SU(2)$-bundles over $S^4$.
