Centralizer Of A Group No two groups function precisely the same – this widespread piece of wisdom is on display day after day in company environments. Although some teams have associates whose strengths and weaknesses perfectly complement one a second, most groups are a lot less harmonious and they are unable to operate alongside one another efficiently.

The ,centralizer, of an ,element, z ,of a group, G is the set of elements of G which commute with z, C_G(z)={x in G,xz=zx}. Likewise, the ,centralizer, of a subgroup H ,of a group, G is the set of elements of G which commute with every ,element, of H, C_G(H)={x in G, forall h in H,xh=hx}. The ,centralizer, always contains the ,group, center of the ,group, and is contained in the corresponding normalizer.

In S3, the ,centralizer, of (1,2,3) is equal to h(1,2,3)i, since it is easy to check that (1,2) does not belong to the ,centralizer,, and by Lagrange’s theorem a proper subgroup ,of a group, with 6 elements can have at most 3 elements. To find the ,centralizer, of (1,2,3) in S4 we have to work a bit harder. Let a = (1,2,3).

The centralizer of an element g in a group G is a subgroup of G. Since the identity e of a group always commutes with every other element, then the centralizer of e is equal to the entire group: C(e) = G.
