摘要:
In this short note we prove that a graph product Gr of finitely generated abelian groups is semicomplete - that is the kernel of the natural homomor- phism Aut(G(Gamma)) -> Aut(G(Gamma)(ab)) induced by the abelianization of G(Gamma)- is equal to the inner automorphisms - if and only if Gamma does not have a separating star.
