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.

The ,centralizer, of an ,element, a ∈ G is defined to be the set C ⁢ ( a ) = { x ∈ G ∣ x ⁢ a = a ⁢ x } Observe that, by definition, e ∈ C ⁢ ( a ) , and that if x , y ∈ C ⁢ ( a ) , then x ⁢ y - 1 ⁢ a = x ⁢ y - 1 ⁢ a ⁢ ( y ⁢ y - 1 ) = x ⁢ y - 1 ⁢ y ⁢ a ⁢ y - 1 = x ⁢ a ⁢ y - 1 = a ⁢ x ⁢ y - 1 , so that x ⁢ y - 1 ∈ C ⁢ ( a ) .
