Code: Quadratic Twists of Elliptic Curves with 3-Isogenies
For the project Three-isogeny Selmer groups and ranks of abelian varieties in quadratic twist families, we provide here some auxiliary code that may be used to compute the bounds on the average rank of elliptic curves, as well as the proportions of rank 0 and rank 1 twists our method produces. Presently, the code below works only for elliptic curves over Q. If you are interested in curves over general number fields, there is code presently being debugged that I hope to post soon.
- Sage code. Please see the file for the relevant commands.
