单群中带有小图像的单词映射

Word maps with small image in simple groups

Matthew Levy

摘要:

我们构造了SL(2; 22 n)中每个n都有小图像的非幂词。特别地,对应的词映射是非满射的。我们还使用它来构造词映射,其值正好是17阶元素的恒等式和单个等价类。在第二部分中,我们构造的词有图像的单位和一个单一的等价类的元素在Alt(n)的所有n的任何等价类的支持大小最多为10。

英文摘要:

We construct non-power words which have small image in SL(2; 22n) for each n. In particular, the corresponding word maps are non-surjective. We also use this to construct word maps whose values are precisely the identity and a single equivalence class of elements of order 17. In the second part we construct words which have image consisting of the identity and a single equivalence class of elements in Alt(n) for all n for any equivalence class with support size at most 10.
