Reconstruction of curves from their theta hyperplanes in genera $6$ and $7$

Algebraic Geometry 2025-05-13 v4

Abstract

We derive a formula for reconstructing a generic complex canonical curve CC of genus 6 and 7 in terms of the theta hyperplanes of CC. Hence, we get a generic inverse to the Torelli map, as well as a complete description of the Schottky locus in these genera. The computational part of the proof relies on a certified numerical argument.
