Hilbert's 10th Problem via Mordell curves

Number Theory 2025-02-20 v2

Abstract

We show that for 5/65/6-th of all primes pp, Hilbert's 10-th Problem is unsolvable for Q(ζ3,p3)\mathbb{Q}(\zeta_3, \sqrt[3]{p}). We also show that there is an infinite set SS of square free integers such tha Hilbert's 10-th Problem is unsolvable over the number fields Q(ζ3,D,p3)\mathbb{Q}(\zeta_3, \sqrt{D}, \sqrt[3]{p}) for every DSD \in S and every prime p2,5(mod9)p \equiv 2,5 \pmod{9}. We use the CM elliptic curves Y2=X3432D2Y^2=X^3-432D^2 associated to the cube sum problem, with DD varying in suitable congruence class, in our proof.
