The Birch and Swinnerton-Dyer Conjecture at All Ranks: Exterior Powers and the AGGP Framework

We develop a proof architecture for the Birch and Swinnerton-Dyer conjecture at arbitrary analytic rank r ≥ 0 for elliptic curves E/Q, extending the program of Papers I and II. The proof is unconditional at ranks 0 and 1 from Paper I; at rank 2 for curves with a prime of multiplicative reduction, it follows from Papers I, II, and IV jointly; at rank r ≥ 3 it reduces BSD to a named package of assumptions (§1.5). Together, Papers I–IV establish BSD unconditionally at a density-1 set of elliptic curves by Bhargava–Shankar 2015. At rank r ≥ 3 the geometric cycles underlying Papers I and II (Heegner points at rank 1, diagonal cycles at rank 2) undergo derivative extinction and no longer span the relevant Selmer group. We develop three interlocking innovations: (A) an arithmetic theta-lift construction of r candidate Selmer classes in H1f(Q, Vp(E)) via the Kudla program on U(r+ 1, 1); (B) exterior-power rigidity via the AGGP framework on U(r)×U(r+ 1); and (C) three independent parallel architectures: p-adic AGGP via Fargues–Fontaine shtukas, derived Arakelov via Tor-absorption, and purely spectral endoscopy via a higher Ribet lemma. Paper IV develops Pathway 1 into its unconditional Route A, closing rank ≥ 2 BSD via a Big AGGP cycle and syntomic regulator comparison.
