Hi all,
I would like to do number field arithmetic in Pari. To be more precise, I would like let Pari do the following job as Sage does,
K.<a> = NumberField(f(x))
L.<b> = NumberField(g(x))
where f(x), g(x) are irreducible polynomials over the rational. I would like to do arithmetic with a,b. This is easily done in Sage. How can I do this by Pari?
Thanks
You can convert the given number field into pari number field with
sage: K.<a> = NumberField(x^2 - 2)
sage: K.pari_nf()
[y^2 - 2, [2, 0], 8, 1,
[[1, -1.41421356237310; 1, 1.41421356237310],
[1, -1.41421356237310; 1, 1.41421356237310],
[1, -1; 1, 1], [2, 0; 0, 4], [4, 0; 0, 2], [2, 0; 0, 1], [2, [0, 2; 1, 0]], []],
[-1.41421356237310, 1.41421356237310], [1, y], [1, 0; 0, 1], [1, 0, 0, 2; 0, 1, 1, 0]]
