how to find the centralizer? | Yahoo Answers

4/10/2012, · Favorite Answer. In group theory, the centralizer of a subset S of a group G is the set of elements of G that commute with each element of S, and the normalizer of S is the set of elements of G...

Centralizer - Art of Problem Solving

A ,centralizer, is part of an algebraic ,structure,.. Specifically, let be a magma, and let be a subset of .The ,centralizer, of is the set of elements of which commute with every ,element, of .. If are subsets of a magma , then .The bicentralizer of is the ,centralizer, of .Evidently, .The ,centralizer, of the bicentralizer, , is equal to , for , but , so . If the magma is associative, then the ...

pactly on a two dimensional euclidean building ∆. The ,centralizer of an element, of Γ is either a Bieberbach group or is described by a ﬁnite graph of ﬁnite cyclic groups. Explicit examples are computed, with ∆ of type Ae 2. 1. Introduction Let Γ be a torsion free discrete group which acts cocompactly on a

COMPONENT GROUPS OF UNIPOTENT CENTRALIZERS IN GOOD ...

Let u2Gbe a unipotent ,element,, and let A(u) = C G(u)=Co G (u) be the group of components (“component group”) of the ,centralizer, of u. We are concerned with the ,structure, of the group A(u) (more precisely: with its conjugacy classes). Consider the set of all triples (1) (L;tZo;u) where Lis a pseudo-Levi subgroup with center Z= Z(L), the coset tZo 2Z=Zo

center of the centralizer of semisimple element - MathOverflow

More precisely, it's a familiar result that the centralizer \$C_G(s)\$ of \$s\$ is generated by some connected subgroups of \$G\$ (including a maximal torus) along with perhaps part of the Weyl group. Moreover, those connected subgroups are enough to generate the identity component \$H\$, which contains all unipotent elements of the centralizer (a relevant issue in characteristic \$p>0\$).

Find the order of the centralizer of the cycle (12345) of ...

4/6/2012, · This follows because conjugating any ,element, in S5 yields another elemnt with the same cycle ,structure, (e.g. 3 cycles are only conjugated to 3 cycles, products of transpositions are only conjugated to products of transposition,etc.). Thus, the ,centralizer, of the cycle (12345) contains all the other 5-cycles in S5 and the identity.
