Let us recall that the size of a conjugacy class is the index of its ,centralizer,. For example, the ,centralizer, of a c3 ,element, in O is C3, hence there are Iol/tc31 = 8 elements in its class.The conclusion from Table 1 is that only the pure rotational groups C,, D,, T, O and I need be considered.

Reflection centralizers in Coxeter groups - arxiv-vanity.com

We give a new proof of Brink’s theorem that the non-reflection part of a reflection ,centralizer, in a Coxeter group is free, and make several refinements. In particular we give an explicit finite set of generators for the ,centralizer, and a method for computing the Coxeter diagram for its reflection part. In many cases, our method allows one to compute centralizers quickly in one’s head. We ...

22/5/2009, · The identity ,element, e is its own conjugacy class; hence we use the convention B e (v,f)≡B(f). Electric charges are labelled by irreps of the ,centralizer, of a conjugacy class of G. The ,centralizer, is defined by N h ={g G|gh=hg}. for S 3, we have , . For a finite group G every representation is equivalent to a unitary representation.

Such an ,element, has type 3A in S (we consider this ,element, in H and then calculate the adjoint character in E8 as described in [6, Table 5.13]). So if L is in D, then it has a 3A ,element, in its ,centralizer, and so L is conjugate to a subgroup of CS y and therefore the two classes ,fuse, in S. Case 694 (2B, 3E, 5G).
