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 in number theory gives a condition for an integer to be a quadratic residue.Although it is not useful computationally, it has theoretical significance, being involved in some proofs of quadratic reciprocity.

See the history of this page for a list of all  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  Gauss' Lemma without Primes. We prove a form of Gauss' lemma which holds in a wider class of rings than the factorial rings: If any two elements of a ring have  Abstract.

Since f is primitive p cannot divide all its coefficients so choose f i to be the first one not The Gauss Lemma and The Eisenstein Criterion Theorem 1 R a UFD implies R[X] a UFD. Proof First, suppose f(X) = a 0 +a 1X +a 2X2 + +a nXn, for a j 2R. Then de ne the content of f(X) to be cont(f(X)) = gcd(a 高斯引理(Gauss lemma )多项式理论的主要命题之一即任意两个本原多项式的乘积仍是一个本原多项式。 [1] 由高斯引理可知，任一非零的整系数多项式如果能够分解为两个次数较低的有理系数多项式的乘积，则它一定能够分解为两个次数较低的整系数多项式的乘积.高斯引理在研究有理系数多项式的因式 Gauss's Lemma for Polynomials is a result in algebra.. The original statement concerns polynomials with integer coefficients.

By Gauss's lemma, it also is irreducible in Q[x]. (b) Adjoining a single root of f to Q does not yet split f because x3 +2 not only has a real root − 3.
