关于阿贝尔群的图积的自同构

On the automorphisms of a graph product of abelian groups

Mauricio Gutierrez, Adam Piggott, Kim Ruane

摘要:

研究有限生成阿贝尔群W的图积的自同构。更确切地说,我们研究了一个自然子群Aut* W的Aut W,与Aut* W = Aut W的顶点群是有限的,并在一些其他情况下。我们证明了一些结构结果,包括Aut* W的半直积分解,其中因子之一是Inn W。我们也给出了一些应用,其中一些是几何性质。

英文摘要:

We study the automorphisms of a graph product of finitely-generated abelian groups W. More precisely, we study a natural subgroup Aut* W of Aut W, with Aut* W = Aut W whenever vertex groups are finite and in a number of other cases. We prove a number of structure results, including a semi-direct product decomposition of Aut* W in which one of the factors is Inn W. We also give a number of applications, some of which are geometric in nature.
