Tropical invariants for binary quintics and reduction types of Picard curves

Algebraic Geometry 2024-10-07 v3 Number Theory

Abstract

We express the reduction types of Picard curves in terms of tropical invariants associated to binary quintics. We also give a general framework for tropical invariants associated to group actions on arbitrary varieties. The problem of finding tropical invariants for binary forms fits in this general framework by mapping the space of binary forms to symmetrized versions of the Deligne-Mumford compactification M0,n\overline{M}_{0,n}.
