|Proposed elldata database at the PARI workshop|
Hello PARI dev, For those of you who where at the PARI/GP workshop at Paris (and for the other I encourage them to read the proceedings here: <http://pari.math.u-bordeaux.fr/Events/IHP2004/>) you might remember that John Cremona proposed to interface his elliptic curves database with PARI/GP. One of the idea was to change ellinit() to accept a curve name as a argument and extract the corresponding curve coefficients from the database. For example we could do: ellinit("11A1") instead of ellinit([0,-1,1,-10,-20]) Before I implement it, I would like to know what other features would be useful in order to store the database in an efficient way. Things I have considered so far: - Retrieving all curves of a given conductor (elllist() ?) - a forell(E=A,B,...) routine that would iterate through all curves of conductors between A and B Ideas ? Opinions ? Comments ? Cheers, Bill.
