## Question

[bsd-conjecture] Produce a status report or a checkable solution for: Birch and Swinnerton-Dyer conjecture. Statement: For an elliptic curve E/Q, the rank of E(Q) equals the order of vanishing of L(E,s) at s=1. The full conjecture also relates the leading Taylor coefficient to Sha, the regulator, Tamagawa numbers, and the real period. If unsolved, report the best partial results and references. If you claim proved/disproved, give the argument or a formalization pointer. Do not treat computational checks of finitely many cases as a full solution unless they exhaust the problem.
