Talk:Coxeter–Dynkin diagram/Comments

From Wikipedia, the free encyclopedia

The content of the page is good. However the notation was (for me) rather non-standard.

In the book "Combinatorics of Coxeter groups" by Bjorner and Brenti (Springer texts in Mathematics) the irreducible Coxeter systems are given in Appendix A1. I believe their notations are much more standard in the literature. For the finite cases they use A_n, B_n, D_n for the families and E_6, E_7, E_8, F_4, G_2, H_3, H_4, I_2(m) for the others. The affine diagrams are \tilde{A}_1, \tilde{A}_{n-1}, \tilde{B}_n, \tilde{C}_n, \tilde{B}_n for the families and \tilde{E}_6, \tilde{E}_7, \tilde{E}_8, \tilde{F}_4, \tilde{G}_2 for the exceptional cases.

I think that using a standard notation, or at the very least making references to standard textbooks, would improve the page considerably.
