Les polynômes permettent de résumer les calculs de base sur les nombres : somme, produit, élévation à une puissance entière. C'est l. a. raison pour laquelle ils se sont si tôt introduits comme outils naturels des mathématiques. Formellement, ils sont utilisés comme des schémas universels pour ces calculs, puisque, par substitution, ils permettent de réaliser tout calcul concret à partir de manipulation abstraite.

This e-book, that is the 1st systematic exposition of the algebraic method of representations of Lie teams through representations of (or modules over) the corresponding common enveloping algebras, became out to be so good written that even at the present time it continues to be one of many major textbooks and reference books at the topic.

12). 15. THEOREM. 1 is nilpotent; (ii) for all x E o. ad x is nilpotent. (i) ~ (ii). 5 (ii). (ii)::::;. (i). Assume that ad xis nilpotent for all xE g. Let g' be a solvable Lie subalgebra of maximal dimension of g; suppose that g' "F g. Consider the adjoint representation of g, and let !! be its restriction to g'. Then g' is stable under g(g'). Let q be the quotient representation of Q in o/g', and (/1 the canonical mapping of 9 onto g/g'. 12). Then yE! g' and [g',y] c g'. Consequently, o' + ky is a Lie subalgebra of g, and [g' + ky, g' + ky] c g', so that g' + ky is solvable.

A) We assume that f! 1 and its proof. - 1(Q(x,)f(y,) + ··· + g(xn)f(yn)). (Xt)f(yj) = 0. I,) (b) We assume that g is simple. Let a= Kerg. Then g = axb, with a and b semi-simple. From (a) there exists v E V such that f(x) = g(x)v for all x E b. Since g(a) = 0, /([a,a]) = 0 by assumption (i). 9), hence f(x) = 0 = g(x)v for all x E a. l,§6] SEMI-SIMPUCITY OF REPRESEl'~TATIONS 23 (c) We consider the general case by induction on dim V. If !! is not simple, let W be a vector subspace of V which is stable under !!

Since g, b and b' have the same rank, the nilspaces of ad9x, ad6x and ad 6,x are equal to a Cartan subalgebra of g. 19. PROPOSITION. Let (g,l)) be a split semi-simple Lie algebra. Let w be an element of the Weyl group operating In {). There exists an elementary = w. automorphism (J of 0 such that n, It is sufficient to consider the case where ex E R exists such that w = s_,. Let X..
