Computing the Weil representation of a superelliptic curve

Number Theory 2023-10-31 v2 Algebraic Geometry

Abstract

We study the Weil representation ρ\rho of a curve over a pp-adic field with potential reduction of compact type. We show that ρ\rho can be reconstructed from its stable reduction. For superelliptic curves of the form yn=f(x)y^n=f(x) at primes pp whose residue characteristic is prime to the exponent nn we make this explicit.
