Conjugacy class - Wikipedia

Definition,. Let G be a group. Two elements a and b of G are conjugate, if there exists an element g in G such that gag −1 = b.One says also that b is a conjugate of a and that a is a conjugate of b.. In the case of the group GL() of invertible matrices, the conjugacy relation is called matrix similarity.. It can be easily shown that conjugacy is an equivalence relation and therefore ...
