CENTRALIZERS OF ELEMENTS IN A GROUP A …

describe all elements having a finitely generated centralizer. It turns out that they are all conjugate to the generator c of Ή. We also prove that the centralizer of each nonidentity element has infinite index in the centralizer of its square. At the same time, the double centralizer of any element is finite.

centralizer and normalizer : definition of centralizer and ...

In group theory, the centralizer of a subset S of a group G is the set of elements of G that commute with each element of S, and the normalizer of S is the set of elements of G that commute with S "as a whole". The centralizer and normalizer of S are subgroups of G, and can provide insight into the structure of G.

centralizers in algebra

A centralizer in an algebra is also called a commutant. This terminology is mostly used in algebras of operatorsin functional analysis. Let Rbe a ring (or an algebra). For every ordered pair(a,b)of elements of R, we can define the additive commutatorof (a,b)to be the element ab-ba, written [a,b].
