Centralizer and normalizer - Infogalactic: the planetary ...

The ,centralizer, and ,normalizer, of S are subgroups of G, and can provide insight into the structure of G. The definitions also apply to monoids and semigroups. In ring theory, the ,centralizer, of a subset of a ring is defined with respect to the semigroup (multiplication) operation of the ring. The ,centralizer, of a subset of a ring R is a subring ...

The double ,centralizer theorem, deals with situations where equality occurs. If S is an additive subgroup of a Lie ring A, then N A (S) is the largest Lie subring of A in which S is a Lie ideal. If S is a Lie subring of a Lie ring A, then S⊆N A (S). See also. Commutant; Stabilizer subgroup; Multipliers and centralizers (Banach spaces) Double ...

In positive characteristic, the normalizer of a (connected) reductive subgroup of a (connected) reductive group is not in general reductive. I communicated the example below in an emailed answer to a query in April 2002 (it took me some searching in old emails to find it!)

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.
