• Wedderburn's little theoremRelated: Noncentral elements are counted using centralizers that are smaller division rings.

• Skolem–Noether theoremRelated: Centralizers help describe the conjugating elements used for embeddings.

• Brauer–Suzuki theoremRelated: Centralizers expose how involutions interact with the rest of the group.

• Feit–Thompson theoremRelated: Centralizers of elements and subgroups help expose the structure of a hypothetical counterexample.
