Turning non-smooth points into rational points

Algebraic Geometry 2024-02-26 v1 Number Theory

Abstract

In a recent paper, the author and St\"ohr established a bound on the number of iterated Frobenius pullbacks needed to transform a non-smooth non-decomposed point on a regular geometrically integral curve into a rational point. In this note we improve this result, by establishing a new bound that is sharp in every characteristic p>0p > 0.
