If you have a question about this talk, please contact Julian Brough. We study an infinite family of quadratic and cubic twists of the elliptic curve E parametrised by the modular curve X0(27). There are two main results, both of which support the validity of the famous Birch– Swinnerton-Dyer conjecture. One of them concerns the 2-adic valuation of the algebraic part of the L-series of quadratic twists of E evaluated at 1, and the other concerns the 3-adic valuations of the L-series of cubic twists of E at 1. We check that the bounds obtained in the main results are precisely the bounds predicted by the conjecture, with equality holding when the Tate–Shafarevich groups of the curves are trivial.
