Hi,
Let K be a number field and O_k denote its ring of integers. For an ideal,
J of O_k, we can have an ideal lattice (I,b_\alpha), where
b_\alpha: J\times J \to Z, b_\alpha(x,y)=Tr(\alpha xy), \forall x,y \in J
and \alpha is a totally positive element of K\{0}.
Suppose now I know J and \alpha, how can I get the generator matrix for the
ideal lattice (J,\alpha) using sage?
Thanks a lot.
Cindy
