全对称集是最近引入的研究群之间同态的工具。本文给出了某些群族中全对称集的完全分类,并给出了另一些群族中全对称集的大小界。因此,我们得到这些群体之间可能的同态的限制。我们的结果的一个例子应用是,任何一个辫子群的同态的直积的可解群必须有循环的形象。
Totally symmetric sets are a recently introduced tool for studying homomorphisms between groups. In this paper, we give full classifications of totally symmetric sets in certain families of groups and bound their sizes in others. As a consequence, we derive restrictions on possible homomorphisms between these groups. One sample application of our results is that any homomorphism of a braid group to a direct product of solvable groups must have cyclic image.
