WebThe naive algorithm to compute equivalent ideals with prime norm is fairly simple, but getting SQISign to work in practice means being very careful with this step. Practically, we want an ideal with prime norm, as we will need to perform computations modulo its norm. When it is prime, computations are easy and efficient.

WebAn ideal. See Ideal(). absolute_norm # Returns the absolute norm of this ideal. In the general case, this is just the ideal itself, since the ring it lies in can’t be implicitly assumed to be an extension of anything. We include this function for compatibility with cases such as ideals in number fields. WebThus, (11) is a prime ideal in Z[√ −5]. 1.2. Comments: Several people stated the correct answer, that (11) is already prime, with-out proof, which is not quite sufficient. Some people incorrectly argued that the norm of a prime ideal must be prime, which is not true: as in the case of (11), the norm of a prime ideal can be the power of a ...

Let A be a Dedekind domain with field of fractions K and integral closure of B in a finite separable extension L of K. (this implies that B is also a Dedekind domain.) Let and be the ideal groups of A and B, respectively (i.e., the sets of nonzero fractional ideals.)
