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
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
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
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
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
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]
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]
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
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).
