Arithmetic and topology of classical structures associated to plane quartics

Olof Bergvall

Published 2021-06-24Version 1

We consider moduli spaces of plane quartics marked with various structures such as Cayley octads, Aronhold heptads, Steiner complexes and G\"opel subsets and determine their cohomology. This answers a series of questions of Jesse Wolfson. We also explore some arithmetic applications over finite fields.
