The exact BSD formula at low Selmer corank

OpenAI's claim

OpenAI presents the following claims relevant to this question, with manuscript numbers following paper order in Sources. In manuscript 1 (family 002; 2026-10-03), the asserted result is that a rational elliptic curve satisfying a Selmer-corank condition of zero or one at one prime satisfies the exact BSD leading-coefficient identity, with every primary factor included.

Mathematical statement of the claimed result

Manuscript 1.
For an elliptic curve $E/\mathbb Q$ and any prime $q$, write $s_q(E)=\operatorname{corank}_{\mathbb Z_q}\operatorname{Sel}_{q^{\infty}}(E/\mathbb Q)$, $r(E)=\operatorname{rank}E(\mathbb Q)$ and $a(E)=\operatorname{ord}_{s=1}L(E,s)$. If $s_q(E)\in\{0,1\}$, the manuscript claims \[ r(E)=a(E)=s_q(E),\qquad\#\operatorname{Sha}(E/\mathbb Q)<\infty, \] and, with $r=r(E)$, \[ \frac{L^{(r)}(E,1)}{r!} =\frac{\Omega_E\operatorname{Reg}_E\,\#\operatorname{Sha}(E/\mathbb Q)\prod_{\ell\text{ finite}}c_{\ell}(E)} {(\#E(\mathbb Q)_{\rm tors})^2}. \] Here $\Omega_E$ is the real Néron period, $\operatorname{Reg}_E$ the Néron--Tate regulator (one in rank zero) and $c_{\ell}$ the Tamagawa numbers. No reduction, torsion, CM or residual-representation conditions are added. The low-Selmer-corank premise remains essential; this is not a claim of unrestricted BSD.

Outline of the argument

For manuscript 1 (family 002; 2026-10-03), the argument tracks the discrepancy between analytic periods and arithmetic determinant volumes in integral cohomology. Residual obstruction tests control vertical prime factors, while character specialization and theta-series comparisons remove horizontal factors; Heegner heights treat the rank-one case.

Formal verification

No Lean formalization is listed at this snapshot for manuscript 1 (family 002; 2026-10-03).

This site has not executed the Lean code. Described statement coverage is not an independent proof check.

Status caveat

The manuscripts were produced by an internal OpenAI model. OpenAI cautions that results without formalization can contain mistakes. This site has not independently checked the proofs; the label records the scope of OpenAI's claim.
