|Re: Class groups|
Now I know PARI doesn't come anywhere near to having a command to do this, so I've been trying to use various bnr commands. Some questions:
1) Is there documentation for the precise structure of the output of bnrinit? Does it actually initialize the class field of a given conductor, or at least give me the relative polynomial?
b) Is there any way of finding the polynomial for a subfield of the ray class field given by a congruence subgroup in the case where the base field is not real (so bnrstark doesn't apply)?
