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.

Resultant and conductor of geometrically semi-stable self maps of the projective line over a number field or function field [PDF]

open access: yes, 2010
We study the minimal resultant divisor of self-maps of the projective line over a number field or a function field and its relation to the conductor. The guiding focus is the exploration of a dynamical analog to Theorem 1.1, which bounds the degree of ...

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 ...

More around Pythagore from ancient to modern times

open access: yes, 2013
This work deals with the history around the ”Pythagorean Theorem“ and the ”Pythagorean Number Triples“ from 2200 B.C. until today. Special emphasis is done on china, including early applications.

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 $\geq 4$.

Birch and Swinnerton-Dyer conjecture in the complex multiplication case and the congruent number problem

open access: yes, 2019
For an elliptic curve $E$ over $K$, the Birch and Swinnerton-Dyer conjecture predicts that the rank of Mordell-Weil group $E(K)$ is equal to the order of the zero of $L(E_{/ K},s)$ at $s=1$.

The Lang-Trotter Conjecture on Average

open access: yes, 2006
For an elliptic curve $E$ over $\ratq$ and an integer $r$ let $\pi_E^r(x)$ be the number of primes $p\le x$ of good reduction such that the trace of the Frobenius morphism of $E/\fie_p$ equals $r$.

On a Conjecture of Cai-Zhang-Shen for Figurate Primes

open access: yes, 2019
A conjecture of Cai-Zhang-Shen for figurate primes says that every integer n > 1 is the sum of two figurate primes. In this paper we give respectively equivalent propositions to the conjecture in the cases of even and odd integers and then confirm the ...
