Reduction of Plane Quartics and Dixmier-Ohno invariants
Published 25 Jan 2024 in math.NT and math.AG | (2401.13902v2)
Abstract: We characterise, in terms of Dixmier-Ohno invariants, the types of singularities that a plane quartic curve can have. We then use these results to obtain new criteria for determining the stable reduction types of non-hyperelliptic curves of genus 3.
