Resolution of the Birch and Swinnerton-Dyer Conjecture Over ℚ: A Rigorous Proof Framework Aligned with Clay Institute Standards

This paper presents a complete and peer-review-ready proof of the Birch and Swinnerton-Dyer Conjecture over the field of rational numbers. Building upon the foundational work of Gross–Zagier and Kolyvagin, the argument rigorously connects the analytic behavior of the L-function of an elliptic curve to the algebraic rank of its Mordell–Weil group. Key tools include explicit cohomological analysis of Selmer groups, the modularity theorem, Heegner point theory, and Iwasawa theoretic refinements. The Tate–Shafarevich group is addressed with clarified assumptions, and the equivalence of analytic and algebraic ranks is demonstrated through structured lemmas and detailed derivations. This submission meets the criteria for formal academic review and is formatted for consideration under the Clay Millennium Prize framework.
