Some explicit arithmetics on curves of genus three and their applications

T Moriya, M Kudo - arXiv preprint arXiv:2209.02926, 2022 - arxiv.org
A Richelot isogeny between Jacobian varieties is an isogeny whose kernel is included in the
$2 $-torsion subgroup of the domain. In particular, a Richelot isogeny whose codomain is …

Reduction of Plane Quartics and Cayley Octads

R van Bommel, J Docking, V Dokchitser… - arXiv preprint arXiv …, 2023 - arxiv.org
We give a conjectural characterisation of the stable reduction of plane quartics over local
fields in terms of their Cayley octads. This results in p-adic criteria that efficiently give the …

Models of hyperelliptic curves with tame potentially semistable reduction

O Faraggi, S Nowell - Transactions of the London Mathematical …, 2020 - Wiley Online Library
Let C be a hyperelliptic curve y 2= f (x) over a discretely valued field K. The p‐adic distances
between the roots of f (x) can be described by a completely combinatorial object known as …

Integral differential forms for superelliptic curves

S Kunzweiler, S Wewers - arXiv preprint arXiv:2003.12357, 2020 - arxiv.org
Given a superelliptic curve $ Y_K: y^ n= f (x) $ over a local field $ K $, we describe the
theoretical background and an implementation of a new algorithm for computing the …

Invariants for trees of non-archimedean polynomials and skeleta of superelliptic curves

PA Helminck - Mathematische Zeitschrift, 2022 - Springer
In this paper we generalize the j-invariant criterion for the semistable reduction type of an
elliptic curve to superelliptic curves X given by y^ n= f (x) yn= f (x). We first define a set of …

Arithmetic of genus three curves and their Jacobians

J Docking - 2023 - discovery.ucl.ac.uk
The Birch–Swinnerton-Dyer Conjecture predicts that, given an abelian variety A over a
number field K, its rank, rk (A/K), is equal to the order of vanishing of its L-function L (A/K, s) …

A generalization of the Newton-Puiseux algorithm for semistable models

PA Helminck - arXiv preprint arXiv:2007.09449, 2020 - arxiv.org
In this paper we give an algorithm that calculates the skeleton of a tame covering of curves
over a complete discretely valued field. The algorithm relies on the {{tame simultaneous …

On invariants of Artin-Schreier curves

J Duque-Rosero, H Goodson, EL García… - arXiv preprint arXiv …, 2024 - arxiv.org
The main goal of this article is to expand the theory of invariants of Artin-Schreier curves by
giving a complete classification in genus 3 and 4. To achieve this goal, we first establish …
