Some Obstructions to Solvable Points on Higher Genus Curves

Number Theory 2025-10-13 v2

Abstract

It is known that for a curve defined over Q\mathbb{Q} of genus g4g \leq 4, there exists a point on the curve defined over a solvable extension of Q\mathbb{Q}. We relate points on curves of genus g5g \geq 5 over solvable extensions to the Bombieri-Lang conjecture. Specifically, we show that varieties parametrising points defined over extensions with a fixed solvable Galois group are of general type. Moreover, we show the existence of certain subvarieties in these varieties imply the existence of solvable morphisms from the curve.
