Popis: | 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 $p > 0$. Comment: 12 pages. Comments are very welcome! |
