Hi.
I have some issue with ideals in number fields. I wanted to test something about cyclotomic polynomials, so I had the following result : sage: N = 25 sage: K.<zeta> = CyclotomicField(N) sage: n = K.degree() sage: ZK = ZZ[zeta] sage: ZK Order in Number Field in zeta0 with defining Polynomial x^20+x^15+x^10+x^5+ 1 sage: I=ZK.ideal(5,zeta-1) sage: I Fractionnal ideal (5,zeta0-1) sage: I.factor() (Fractionnal ideal (5,zeta0-1))^20 sage: I==I^20 False sage: zeta0 1 sage: zeta zeta I think there is a problem with the zeta0 (actually I tried to enforce the name of the ZK variable by ZK.<zeta_int> = ZZ[zeta] or ZK.<zeta0> = ZZ[zeta] or ZK.<zeta> = ZZ[zeta] but that doesn't work : it gives the same result. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
