Groups with Few Normalizer Subgroups

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 [10]). 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, …

LINEAR ALGEBRAIC GROUPS WITHOUT THE NORMALIZER THEOREM ...

and the ,normalizer theorem, (a Borel subgroup is self-normalizing). The main idea is a new approach to the structure of rank 1 groups; the key step is lemma 5. All algebraic geometry is over a ﬁxed algebraically closed ﬁeld. G always denotes a connected linear algebraic group with Lie algebra g, T a maximal torus, and B a Borel subgroup ...

The normalizer of the Weyl group

The ,normalizer, is described algebraically in ,Theorem, 1.3 as an extension of two groups defined (almost) explicitly in terms of the group of units of R and the group of automorphisms of the Coxeter graph of G. Two consequences of ,Theorem, 1.3 are mentioned in Corollary 1.6 and Corollary 1.7.
