Webfrom Euclid’s algorithm by the unit −1 to get: 6 = 750(5)+144(−26) Definition: An element pof positive degree in a Euclidean domain is prime if its only factors of smaller degree are units. Example: In F[x], the primes are, of course, the prime polynomials. The integer primes are pand −p, where pare the natural number primes.

WebThen the polynomial ring k[X] is Euclidean, hence a PID, hence a UFD. Recall that the polynomial norm is N : k[X] f 0g! Z 0; Nf= deg(f): Note that nonzero constant polynomials have norm 0. Sometimes we de ne N0 = 1 as well. The veri cation that the k[X]-norm makes k[X] Euclidean is a matter of poly-
WebED implies PID implies UFD. Theorem: Every Euclidean domain is a principal ideal domain. Proof: For any ideal I, take a nonzero element of minimal norm b .
