28/7/2009, · ,For any element a in any group G , prove that is a subgroup of C(a) , the centralizer of a, .? Math 103 HW 6 Solutions to Selected Problems

For any element a in any group G, prove that < a > is a subgroup of C(a) (the centralizer of a,). Solution: < a > is already a ,group, under the multiplication in ,G,, so we just need to show it is a subset ,of C,(a). This is easy: a a = a a, so a 2C(a). As ,C,(a) is a ,group Finite groups and subgroups - part 2 | JoeQuery

Definition (,Subgroup,). If a subset H of a ,group G, is itself a ,group, under the operation of ,G,, we say that H is a ,subgroup, of ,G,, denoted H ,G,. If H is a proper subset of ,G,, then H is a proper ,subgroup, of ,G,. {e} is thetrivialsubgroupofG. If H 6= {e} andH ,G,, H is callednontrivial. Theorem (3.1 — One-Step ,Subgroup, Test). Let ,G, be a ,group, and ; 6= 2.2 The centre centralizers and conjugacy

Let ,G, be a ,group,. Then Z(,G,) is a ,subgroup, of ,G,. Proof. We have the usual three things to show, and we must use the deﬁnition of the centre to show them. • Z(,G,) is closed under the operation of ,G,. Suppose a,b ∈ Z(,G,). We must show that ab ∈ Z(,G,). That means showing that ,for any element, x of ,G,, x commutes with ab. Now abx = axb (bx = xb ... Prove that $\\left$ is a subgroup of $C(a)$
