我们定义了连通简单图的自由积,当图是顶点传递时,它与已有的几个定义等价,但在其他情况下则不同。新的定义是为了使自由积的自同构群尽可能大而设计的,并给出了它是非离散的充分准则。最后,我们将Tits的树自同构分类和简单性准则应用于图的自由积。
We define a free product of connected simple graphs that is equivalent to several existing definitions when the graphs are vertex-transitive but differs otherwise. The new definition is designed for the automorphism group of the free product to be as large as possible, and we give sufficient criteria for it to be non-discrete. Finally, we transfer Tits' classification of automorphisms of trees and simplicity criterion to free products of graphs.
