Strong Birch–Swinnerton-Dyer formula in the everywhere-good-reduction case

Let AA be an abelian variety of dimension gg over a number field FF, assume that AA has good reduction everywhere, and let PA,(η)P_{A,\infty}(\eta) and aη\mathfrak a_\eta be the archimedean period and associated fractional ideal used to define the global volume. Let AtA^t be the dual abelian variety, let ΘNT(A)\Theta_{NT}(A) be the Néron–Tate regulator, and let \Sha(A/F)\Sha(A/F) be the Tate–Shafarevich group. Everywhere-good-reduction strong BSD formula. One has

L(A,1)=PA,(η)NF/Q(aη)ΘNT(A)[\Sha(A/F)]dFg/2[A(F)tor][At(F)tor].L^*(A,1)=\frac{P_{A,\infty}(\eta)\,\mathbb N_{F/\mathbb Q}(\mathfrak a_\eta)\,\Theta_{NT}(A)\,[\Sha(A/F)]}{|d_F|^{g/2}[A(F)_{\mathrm{tor}}][A^t(F)_{\mathrm{tor}}]}.

This is the strong BSD formula after the finite period factor becomes 11 under everywhere good reduction. It is a specialization of the preceding conjecture, and the source gives no resolution beyond that of the general BSD conjecture.
