Relationship between Tate-Shafarevich group and the BSD conjecture

Firstly, the functional field result your state is due to Tate in his Bourbaki talk. In fact he proves that the finiteness of the $p$-primary part of Sha is enough for $p$ different from the character …

integral basis for the Lie algebra of the Neron model of an abelian variety

The same problem already appears in the formulation of the Birch and Swinnerton-Dyer conjecture for say an elliptic curve over a number field. When there is no longer a global minimal Weierstrass mode …

Is the leading Taylor coefficient at $s = 1$ of the $L$-series of an elliptic curve over $\m...

Let me summarise the comments above that give a full answer (correct me if I am wrong). The analytic continuation of $L(E,\bar{s})=\overline{L(E,s)}$ shows that $c\in\mathbb{R}$. If $r=0$, the fact …

Deducing BSD from Gross-Zagier and Kolyvagin

Let $E/\mathbb{Q}$ be an elliptic curve of analytic rank $0$ or $1$. Then indeed the rank part of the BSD conjecture is known, but the exact formula for the leading term is not yet fully proven. The $ …
