Talk:En (Lie algebra)

From Wikipedia, the free encyclopedia

E₃ through E₈ are not the same class of object as the other examples; they are irreducible Lie algebras. they should not be confused with the other examples.There is a fundamental theorem that there are only five sporadic Dynkin diagrams: E₆ through E₈, F₄ G₂.

I don't mind dividing, but I supported R.e.b.'s revert because I didn't like your choice of section titles. I just changed them to something that seems better. Michael Kinyon 07:40, 6 October 2006 (UTC)
