Introduction to Group Theory for Physicists

Centralizer, of an Element of a Group c G(a) The ,centralizer, of a, c G(a) is a new subgroup in Gformed by ga= ag, i.e. the set of elements of Gwhich commutes with a. 4This is pronounced Gmod N. 5An abelian group is one which the multiplication law is commutative g 1 2 = 2 1. 6We will see that semi-simple Lie groups are direct sum of simple Lie ...

In other words, that the centralizer is the set of all the elements that commute with σ, and I also know that if two permutations have disjoint cycles it implies that they commute, but the thing is; there are no τ ∈ S n s.t. τ and σ have disjoint cycles, since σ = ( 1 2 3... n).

Conjugacy class - Wikipedia

In mathematics, especially group theory, two elements a and b of a group are conjugate if there is an element g in the group such that b = g –1 ag.This is an equivalence relation whose equivalence classes are called conjugacy classes.. Members of the same ,conjugacy class, cannot be distinguished by using only the group structure, and therefore share many properties.
