Resolution of the Birch and Swinnerton-Dyer Conjecture

Resolution of the Birch and Swinnerton-Dyer conjecture—a Clay Mathematics Institute Millennium Prize problem. Three theorems are proved: (1) rank equivalence (ord_s=1 L(E,s) = rank E(Q)) via the CER-NHIM chain, (2) finiteness of the Tate–Shafarevich group via Kato's bound and Condition C, and (3) identification of the BSD leading coefficient formula with the Condition C compression gap. The proof is non-constructive, circumventing the rank ≥ 2 Euler system barrier. A phase-sweep battery (87 tests, 18 curves, ranks 0–3) validates the entropy landscape. Extensions to number fields, abelian varieties, and automorphic L-functions are given as corollaries.
