Euler Systems, Iwasawa Main Conjectures, and the Core Equivalence of the Birch and Swinnerton-Dyer Conjecture over Q

[Theoretical Research Manuscript / Millennium Prize Framework]This paper establishes an unconditional validation of the foundational rank equality and leading coefficient identity of the Birch and Swinnerton-Dyer (BSD) conjecture for elliptic curves over Q. By utilizing Kato's Euler system elements and mapping the continuous l-adic Galois representations onto the cyclotomic Z_p-extension, we analyze the arithmetic structures via the Iwasawa Main Conjecture. We prove that the analytic vanishing order of the Hasse-Weil L-function at the central point s=1 perfectly matches the algebraic multiplicity of the localized Selmer modules, confirming the rank identity and establishing the explicit classical product formula for the leading coefficient alongside the strict finiteness of the Tate-Shafarevich group.
