Hello group, I am playing with rings which look like K = Q[X]/<Phi_m(X)> with any large value m. Unfortunately I cannot use NumberField() because it's too long. I get around this by using quotient which is a little bit faster:
m = 3*5*7*11 Q.<x> = QQ['x'] Phi_m = cyclotomic_polynomial(m) K.<k> = Q.quotient(Phi_m) What I want to do is a way to evaluate polynomials of K in a power of a primitive square root of unity: omega = CC(e^(2*I*pi/m)) F = Hom(K, CC) f = F([omega]) TypeError: images do not define a valid homomorphism Does anyone see another way to do this?
