Centralizers in graph products of groups

• inﬁnite cyclic generated by an ,element, β such that βm =g for some m(if g is not conjugate to any ,element, of any Gi). In this paper, the main results (Theorems 32 and 52) are that for graph products, the ,centralizer of an element, is the direct product of a full subgroup (see Deﬁnition 55) of the graph product

center/centralizer of a group? abelian? | Yahoo Answers

13/9/2007, · An easy counterexample is to take G a nonabelian group, and look at the ,centralizer, of the identity ,element,, which easy to show to be G. The answer to the second question is yes. If a and b are any two elements of the center, then by definition of the center a commutes with b, so ab=ba for any two a and b in the center of G.
