Abstract
Let g be a complex simple Lie algebra and let G be the adjoint group of g. It is by now classical that the Poincaré polynomial p G (t) of G factors into the form

R. Steinberg, “Finite reflection groups,” Transactions of the American Mathematical Society, vol. 91 (1959), pp. 493–504. As we have noted in the Introduction a proof (see Corollary 8. 7) of the procedure is a consequence of our main results. The paper [15] is mainly devoted to giving a proof of two empirical discoveries of H. S. M. Coxeter. A proof of these discoveries is also given here (see Theorem 8. 4) ).
