On the rank of the fibers of elliptic K3 surfaces [PDF]

open access: yes, 2013
Let $X$ be an elliptic K3 surface endowed with two distinct Jacobian elliptic fibrations $\pi_i$, $i=1,2$, defined over a number field $k$. We prove that there is an elliptic curve $C\subset X$ such that the generic rank over $k$ of $X$ after a base ...

On the largest element in D(n)-quadruples

open access: yes, 2019
Let $n$ be a nonzero integer. A set of nonzero integers $\{a_1,\ldots,a_m\}$ such that $a_ia_j+n$ is a perfect square for all $1\leq ...

Constructing families of moderate-rank elliptic curves over number fields [PDF]

open access: yes, 2017
We generalize a construction of families of moderate rank elliptic curves over $\mathbb{Q}$ to number fields $K/\mathbb{Q}$. The construction, originally due to Steven J.

The yoga of the Cassels-Tate pairing

open access: yes, 2007
Cassels has described a pairing on the 2-Selmer group of an elliptic curve which shares some properties with the Cassels-Tate pairing.

Self-duality of Selmer groups

open access: yes, 2008
The first part of the paper gives a new proof of self-duality for Selmer groups: if A is an abelian variety over a number field K, and F/K is a Galois extension with Galois group G, then the Q_pG-representation naturally associated to the p-infinity ...

When are Multiples of Polygonal Numbers again Polygonal Numbers?

open access: yes, 2018
Euler showed that there are infinitely many triangular numbers that are three times other triangular numbers. In general, it is an easy consequence of the Pell equation that for a given square-free m > 1, the relation P=mP' is satisfied by infinitely ...

Sums of two biquadrates and elliptic curves of rank $\geq 4$ [PDF]

open access: yes, 2012
If an integer $n$ is written as a sum of two biquadrates in two different ways, then the elliptic curve $y^2=x^3-nx$ has rank $\geq 3$. If moreover $n$ is odd and the parity conjecture is true, then it has even rank $\geq 4$.
