Rank = ord L(E,1)
Rank = ord L(E,1)
For every elliptic curve E over ℚ, the rank of the Mordell–Weil group E(ℚ) equals the order of vanishing of the Hasse–Weil L-function L(E,s) at s = 1. Finiteness of Sha is part of the expected picture.
BSD —gate→ Rank = ord L(E,1)
Ш finiteness —implies→ Rank = ord L(E,1)
L-function —implies→ Rank = ord L(E,1)
