centralizer in nLab

The centralizer of S S is clearly a subgroup of its normalizer C G ( S ) ⊂ N G ( S ) C_G(S) \subset N_G(S) as fixing the set g H = H g g H = H g is a weaker requirement than g h = h g g h=h g for all h ∈ H h\in H .

The centralizer Cen(h’i) of ’in Out(F r) is a subgroup of Stab(+’), see Lemma 2.21. Moreover, the normalizer N(h’i) of h’iin Out(F r) has a subgroup of index at most 2 which is contained in Stab(+ ’). With this relationship in mind, the result of [BFH97] can be reinterpreted as saying that the groups Stab(+

Centers and centralizers

Given g 2G, the centralizer of g in G is the subgroup C G(g) := fa 2G jag = gag. Given S G, the centralizer and the normalizer of S are the subgroups C G(S) := fa 2G jag = ga 8g 2Sgand N G(S) := fa 2G jaSa 1 = Sg. Two elements g;h 2G are conjugate when there exists a 2G such that h = aga 1. The conjugacy class of g in G is the set K G(g) := faga 1 ja 2Gg.
