Groups of generalized G‐type and applications to torsion subgroups of rational elliptic curves over infinite extensions of Q

open access: yesTransactions of the London Mathematical Society, 2019
Recently, there has been much interest in studying the torsion subgroups of elliptic curves base‐extended to infinite extensions of Q. In this paper, given a finite group G, we study what happens with the torsion of an elliptic curve E over Q when ...

Non‐vanishing theorems for central L‐values of some elliptic curves with complex multiplication

open access: yesProceedings of the London Mathematical Society, Volume 121, Issue 6, Page 1531-1578, December 2020., 2020
Abstract The paper uses Iwasawa theory at the prime p=2 to prove non‐vanishing theorems for the value at s=1 of the complex L‐series of certain quadratic twists of the Gross family of elliptic curves with complex multiplication by the field K=Q(−q), where q is any prime ≡7mod8.

Models of hyperelliptic curves with tame potentially semistable reduction

open access: yesTransactions of the London Mathematical Society, Volume 7, Issue 1, Page 49-95, December 2020., 2020
Abstract Let C be a hyperelliptic curve y2=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 the cluster picture. We show that the cluster picture of C, along with the leading coefficient of f and the action of Gal(K¯/K) on the roots of f, completely ...

Conductor and discriminant of Picard curves

open access: yesJournal of the London Mathematical Society, Volume 102, Issue 1, Page 368-404, August 2020., 2020
Abstract We describe normal forms and minimal models of Picard curves, discussing various arithmetic aspects of these. We determine all so‐called special Picard curves over Q with good reduction outside 2 and 3, and use this to determine the smallest possible conductor a special Picard curve may have.

Torsion subgroups of rational Mordell curves over some families of number fields

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022
Mordell curves over a number field K are elliptic curves of the form y2 = x3 + c, where c ∈ K \ {0}. Let p ≥ 5 be a prime number, K a number field such that [K : ℚ] ∈ {2p, 3p}.

L‐equivalence for degree five elliptic curves, elliptic fibrations and K3 surfaces

open access: yesBulletin of the London Mathematical Society, Volume 52, Issue 2, Page 395-409, April 2020., 2020
Abstract We construct non‐trivial L‐equivalence between curves of genus one and degree five, and between elliptic surfaces of multisection index five. These results give the first examples of L‐equivalence for curves (necessarily over non‐algebraically closed fields) and provide a new bit of evidence for the conjectural relationship between L ...

Base change for Elliptic Curves over Real Quadratic Fields [PDF]

open access: yes, 2014
Let E be an elliptic curve over a real quadratic field K and F/K a totally real finite Galois extension. We prove that E/F is modular.Comment: added a short proof of Proposition 2.1 and a few more small changes to improve ...

Toroidal and Annular Dehn Fillings [PDF]

open access: yes, 1997
Suppose that M is a hyperbolic 3‐manifold which admits two Dehn fillings M(r1) and M(r2) such that M(r1) contains an essential annulus, and M(r2) contains an essential torus. It is known that Δ = Δ (r1, r2) ⩽ 5.

GOLDFELD’S CONJECTURE AND CONGRUENCES BETWEEN HEEGNER POINTS

open access: yesForum of Mathematics, Sigma, 2019
Given an elliptic curve $E$ over $\mathbb{Q}$, a celebrated conjecture of Goldfeld asserts that a positive proportion of its quadratic twists should have analytic rank 0 (respectively 1).
