Split degenerate superelliptic curves and $ℓ$ -adic images of inertia

Jeffrey Yelton

Let $K$ be a field with a discrete valuation, and let $p$ and $ℓ$ be (possibly equal) primes which are not necessarily different from the residue characteristic. Given a superel…

Branch points of split degenerate superelliptic curves II: on a conjecture of Gerritzen and van der Put

Jeffrey Yelton

Let $K$ be a field with a discrete valuation, and let $p$ be a prime. It is known that if $Γ ⊲ Γ_{0} < PGL_{2} (K)$ is a Schottky group normally contained in a larger group w…

Branch points of split degenerate superelliptic curves I: construction of Schottky groups

Jeffrey Yelton

Let $K$ be a field with a discrete valuation, and let $p$ be a prime. It is known that if $Γ ⊲ Γ_{0} < PGL_{2} (K)$ is a Schottky group normally contained in a larger group w…

Clusters and semistable models of hyperelliptic curves in the wild case

Leonardo Fiore, Jeffrey Yelton

Given a Galois cover $Y \to X$ of smooth projective geometrically connected curves over a complete discrete valuation field $K$ with algebraically closed residue field, we define a…

Divisibility of torsion subgroups of abelian surfaces over number fields

John Cullinan, Jeffrey Yelton

Let $A$ be a 2-dimensional abelian variety defined over a number field $K$ . Fix a prime number $ℓ$ and suppose $# A (F_{p}) \equiv 0 (mod ℓ^{2})$ for a set of primes $\m…

Semistable models of elliptic curves over residue characteristic 2

Jeffrey Yelton

Given an elliptic curve $E$ in Legendre form $y^{2} = x (x - 1) (x - λ)$ over the fraction field of a Henselian ring $R$ of mixed characteristic $(0, 2)$ , we present an algorithm for d…

Lifting images of standard representations of symmetric groups

Jeffrey Yelton

We investigate closed subgroups $G \subseteq Sp_{2 g} (Z_{2})$ whose modulo- $2$ images coincide with the image $\mathfrak{S}_{2g + 1} \subseteq \mathrm{Sp}_{2g}(\math…

An abelian subfield of the dyadic division field of a hyperelliptic Jacobian

Jeffrey Yelton

Given a field $k$ of characteristic different from $2$ and an integer $d \geq 3$ , let $J$ be the Jacobian of the "generic" hyperelliptic curve given by $y^2 = \prod_{i = 1}^d (x -…

A note on 8-division fields of elliptic curves

Jeffrey Yelton

Let $K$ be a field of characteristic different from $2$ and let $E$ be an elliptic curve over $K$ , defined either by an equation of the form $y^{2} = f (x)$ with degree $3$ or as th…

Boundedness results for 2-adic Galois images associated to hyperelliptic Jacobians

Jeffrey Yelton

Let $K$ be a number field, and let $C$ be a hyperelliptic curve over $K$ with Jacobian $J$ . Suppose that $C$ is defined by an equation of the form $y^{2} = f (x) (x - λ)$ for some ir…

Dyadic torsion of 2-dimensional hyperelliptic Jacobians

Jeffrey Yelton

Let $k$ be a field of characteristic $0$ , and let $α_{1}$ , $α_{2}$ , ..., $α_{5}$ be algebraically independent and transcendental over $k$ . Let $K$ be the transcendental extension o…

Images of 2-adic representations associated to hyperelliptic Jacobians

Jeffrey Yelton

Let $k$ be a subfield of $C$ which contains all $2$ -power roots of unity, and let $K = k (α_{1}, α_{2}, ..., α_{2 g + 1})$ , where the $α_{i}$ 's are independent and transcen…
