Gauss (1801) proved this when A= Z. Note that the case where A= Z and degg= 1 is the rational root theorem (actually proving the rational root theorem in that manner would be circular though, since one usually uses the rational root theorem to show that Z is integrally closed). Proof of Gauss’s Lemma.

Definition of gradient in a Riemannian manifold. Hot Network Questions Gauss' Lemma for Monic Polynomials. What is often referred to a Gauss' Lemma is a particular case of the Rational Root Theorem applied to monic polynomials (i.e., polynomials with the leading coefficients equal to 1.): Every real root of a monic polynomial with integer coefficients is either an integer or irrational. Gauss's lemma can therefore be stated as , where is the Legendre symbol.

( Gauss's Lemma) Let p be an odd prime, $(a, p) = 1$ . Let k be the number of least positive residues of.

The lemma allows the exponential map to be understood as a radial isometry , and is of fundamental importance in the study of geodesic convexity and normal coordinates . Integral Domains, Gauss' Lemma Gauss' Lemma We know that Q[x], the polynomials with rational coefficients, form a ufd, simply because the rationals form a field.But a given polynomial, and all its factors, can be mapped into Z[x] simply by multiplying through by the common denominator.

In algebra, Gauss's lemma, named after Carl Friedrich Gauss, is a statement about polynomials over the integers, or, more generally, over a unique factorization domain (that is, a ring that has a unique factorization property similar to the fundamental theorem of arithmetic).

Otherwise, the following facts are lacking, and must appear in the article The existence, in any GCD domain, of a factorization of every polynomial into primitive part and content, which is unique up to units, and is compatible with products.

Factorizing polynomials with rational coefficients can be difficult and Gauss's Lemma is a helpful tool for this problem. It is used implicitly in computer algebra packages. Theorem A polynomial with integer coefficients that is irreducible in Z[x] is irreducible in Q[x] .
