If a ∈ Z and p is prime, then ap ≡ a (mod p). … Given a Gaussian integer z0, called a modulus, two Gaussian integers z1,z2 are congruent modulo z0, if their difference is a multiple of z0, that is if there exists a Gaussian integer q such that z1 − z2 = qz0. In other words, two Gaussian integers are congruent modulo z0, if their difference belongs to the ideal generated by z0. This is denoted as z1 ≡ z2 (mod z0).

WebIn Z the ideal h6i= f6b: b2Zgis all multiples of 6. In Q[x] the ideal hxi= ffx: f2 Q[x]gis all polynomials in Q[x] divisible by x. Example 1.1.6. Find all ideals in Z 6. One way to do this is to start with f0gand consider including each non-zero element of Z 6 and adding elements until the set is closed under + and see if we have an ideal. WebFACTORING INTEGER PRIMES IN Z[i] We have seen that an integer prime p (as an element of Z[i]) is either a Gaussian prime or a product of two conjugate Gaussian primes: p = ˇ ˇ. In the latter case, writing ˇ= a + bi with a and b integers, we get p = a2 + b2, a sum of two squares. Conversely, suppose p = a2 + b2 for a and b integers. Then ...
