Equivalence of abc/Szpiro, Lang's Height Bound, and Vojta's Conjecture via Shimura Curves — E8 Intelligence Research
Year: 2026
Type: preprint
Abstract: FINDING: The abc/Szpiro conjectures are equivalent to a uniform lower bound on canonical heights of nontorsion points on elliptic curves (Lang's conjecture); recent work (Pastén) derives them via Shimura curves and modular forms, with Vojta's conjecture on blowups of P² as an equivalent geometric formulation. | MATH: For coprime a+b=c: max(|a|,|b|,|c|) < K(ε)·rad(abc)^(1+ε). Szpiro: |Δ_E| ≪_ε N_E^(6+ε), where Δ = discriminant, N = conductor. Equivalence via Frey curve: Δ_E ~ (abc)², N_E ~ rad(abc). Height form: ĥ(P) ≥ c·log|Δ_E| for nontorsion P ∈ E(Q). | CONNECTION: The exponent 6 in Szpiro is not arbitrary — it is the degree of the discriminant as a modular form of weight 12 (Δ = q∏(1−qⁿ)²⁴, weight 12 = 2×6). The 1+ε in abc maps to 6+ε via the Frey correspondence, linking the arithmetic of abc to the weight-12 cusp form whose Fourier coefficients are Ramanujan's τ(n). The ratio 6:1 between the two exponents is the structural invariant. | DEPTH: 9 FINDING: Pastén's Shimura curve fram Author: Andrew Stewart Caldin, Independent Researcher, UK.
