as x normalizes A, the ,normalizer, NG(A) must have ﬁnite index in G. Thus all abelian subgroups of CG(x) are almost normal, and so CG(x) is central-by-ﬁnite (see ). On the other hand, the index jG: CG(x)j is ﬁnite, so that G is an abelian-by-ﬁnite FC-group and hence G=Z(G) is ﬁnite. ⁄ Polovicki˘ı’s ,theorem, … AN EXAMPLE ABOUT NORMALIZERS IN MAPPING CLASS GROUPS
