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

22 Mar 2013 That is, n n is a quadratic residue modulo p p when u u is even and it is a quadratic nonresidue when u u is odd. Gauss' Lemma is the special

If a primitive polynomial f(x) ∈ Z[x] is reducible over Q then it is reducible over Z. Proof. Let f(x) = u(x)v(x) where Along the way, we shall prove Gauss' Lemma that the product of primitive polynomials in a UFD is itself primitive. (Recall that a polynomial over a UFD is said to av CG ALLANDER · 1974 — x = 2), men x2 s 7 (mod 11) olösbar . Gauss' lemma: Låt p vara ett udda primtal och a ett heltal, relativt primisk till p.

Math 121. Eisenstein criterion and Gauss’ Lemma Let Rbe a UFD with fraction eld K. The aim of this handout is to prove an irreducibility criterion in K[X] due to Eisenstein: if f = a nXn + + a 0 2R[X] has positive degree nand ˇis a prime of Rwhich does not divide a n but does divide a i for all i

1. Gauss’ Lemma - Tomorrow we’ll prove the famous and enormously useful Quadratic Reciprocity Law, which deals with the Legendre symbol for odd primes. - Our goal today is to understand it for the prime 2. - Namely, what is 2 p ? This takes a little more work than you think. Theorem 1. (Gauss’ Lemma) Let pbe an odd prime and aan integer

(Gauss’ Lemma) Let pbe an odd prime and aan integer GAUSS' LEMMA HWA TSANG TANG Abstract. Let f(x) be a polynomial in several indeterminates with coefficients in an integral domain R with quotient field K. We prove that the principal ideal generated by/in the polynomial ring R[x] is prime iff/is irreducible over K and A_1=R where A is the content off.
