Parity conjectures for elliptic curves over global fields of positive characteristic [PDF]

open access: yesCompositio Mathematica, 2010
We prove the $p$-parity conjecture for elliptic curves over global fields of characteristic $p > 3$. We also present partial results on the $\ell$-parity conjecture for primes $\ell \neq p$.Comment: to be published in Compositio Mathematica. This version

On ring class eigenspaces of Mordell-Weil groups of elliptic curves over global function fields

open access: yesJournal of Number Theory, 2008
If E is a non-isotrivial elliptic curve over a global function field F of odd characteristic we show that certain Mordell-Weil groups of E have 1-dimensional eigenspace relative to a fixed complex ring class character provided that the projection onto ...

Most elliptic curves over global function fields are torsion free [PDF]

open access: yesActa Arithmetica, 2022
Given an elliptic curve $E$ over a global function field $K$, the Galois action on the $n$-torsion points of $E$ gives rise to a mod-n Galois representation $ρ_{E,n}$. For $K$ satisfying some mild conditions, we show that the set of $E$ for which $ρ_{E,n}$ is as large as possible for all $n$, has density $1$.

Heegner Points and the Rank of Elliptic Curves over Large Extensions of Global Fields [PDF]

open access: yesCanadian Journal of Mathematics, 2008
AbstractLetkbe a global field,a separable closure ofk, andGkthe absolute Galois groupofoverk. For everyσ ∈ Gk, letbe the fixed subfield ofunderσ. LetE/kbe an elliptic curve overk. It is known that the Mordell–Weil grouphas infinite rank. We present a new proof of this fact in the following two cases.

On the Average of p-Selmer Ranks in Quadratic Twist Families of Elliptic Curves Over Global Function Fields

open access: yesInternational Mathematics Research Notices, 2023
Abstract Let $\mathbb{F}_{q}$ be a finite field whose characteristic is relatively prime to $2$ and $3$. Let $p$ be a prime number that is coprime to $q$. Let $E$ be an elliptic curve over the global function field $K = \mathbb{F}_{q}(t)$ such that $\textrm{Gal}(K(E[p])/K)$ contains the special linear group $\textrm{SL}_{2}(\mathbb{F}_{p}

First and second K-groups of an elliptic curve over a global field of positive characteristic [PDF]

open access: yesAnnales de l'Institut Fourier, 2018
In this paper, we show that the maximal divisible subgroup of groups K 1 and K 2 of an elliptic curve E over a function field is uniquely divisible. Further those K-groups modulo this uniquely divisible subgroup are explicitly computed. We also calculate the motivic cohomology groups of the minimal regular model of E, which is an elliptic surface ...

Densities for Elliptic Curves over Global Function Fields

open access: yes, 2023
Let $K$ be a global function field. We obtain a set of formulas for the densities of the Kodaira types and Tamagawa numbers of elliptic curves over a completion of $K$ that is independent of the field's characteristic. Furthermore, for a finite field $F$ and real numbers $s$ and $ε$ such that $s>1$ and $ε>0$, we prove that there exists a global ...

Structure of Tate–Shafarevich groups of elliptic curves over global function fields [PDF]

open access: yesKyoto Journal of Mathematics, 2015
The structure of the Tate-Shafarevich groups of a class of elliptic curves over global function fields is determined. These are known to be finite abelian groups from the monograph [1] and hence they are direct sums of finite cyclic groups where the orders of these cyclic components are invariants of the Tate-Shafarevich group.

Quadratic Chabauty for (bi)elliptic curves and Kim's conjecture

open access: yes, 2020
We explore a number of problems related to the quadratic Chabauty method for determining integral points on hyperbolic curves. We remove the assumption of semistability in the description of the quadratic Chabauty sets $\mathcal{X}(\mathbb{Z}_p)_2 ...
