利用实半解析集的曲线选择引理的一个强形式,证明了对任意连通李群G,G中所有n阶元的集合EN(G)的每个连通分支都是G中的共轭类,特别地,G中所有有限阶共轭类都是闭的.给出了En(G)的连通分支的一些性质。
Using a strong version of the Curve Selection Lemma for real semianalytic sets, we prove that for an arbitrary connected Lie group G, each connected component of the set En(G) of all elements of order n in G is a conjugacy class in G. In particular, all conjugacy classes of finite order in G are closed. Some properties of connected components of En(G) are also given.
