WebCorollary 2.3 (The Jordan-Chevalley decomposition) If xis an endomorphism on V, then x = x s+ x n, where x s and x n have the following properties: the roots of the minimal polynomial of x s are distinct, x n is nilpotent, and x s and x n commute. Further, x s and x n are the unique operators that satisfy these properties. Pf. By Proposition (2 ... In number theory, the Chevalley–Warning theorem implies that certain polynomial equations in sufficiently many variables over a finite field have solutions. It was proved by Ewald Warning (1935) and a slightly weaker form of the theorem, known as Chevalley's theorem, was proved by Chevalley (1935). Chevalley's theorem implied Artin's and Dickson's conjecture that finite fields are quasi-algebraically closed fields (Artin 1982, page x).
