Averages of elliptic curve constants [PDF]

open access: yesarXiv, 2007
We compute the averages over elliptic curves of the constants occurring in the Lang-Trotter conjecture, the Koblitz conjecture, and the cyclicity conjecture. The results obtained confirm the consistency of these conjectures with the corresponding ``theorems on average'' obtained recently by various authors.

Classifying Brumer's quintic polynomials by weak Mordell-Weil groups [PDF]

open access: yesarXiv, 2008
We develop a general classification theory for Brumer's dihedral quintic polynomials by means of Kummer theory arising from certain elliptic curves. We also give a similar theory for cubic polynomials.

An explicit classification for the cyclic rational torsion subgroups of odd order of elliptic curves over $ \Q $ [PDF]

open access: yesarXiv, 2008
This paper has been withdrawn by the author due to an uninteresting calculation.

Rational torsion in elliptic curves and the cuspidal subgroup [PDF]

open access: yesarXiv, 2008
Let $A$ be an elliptic curve over $\Q$ of square free conductor $N$. We prove that if $A$ has a rational torsion point of prime order $r$ such that $r$ does not divide $6N$, then $r$ divides the order of the cuspidal subgroup of $J_0(N)$.

Period and index of genus one curves over number fields [PDF]

open access: yesarXiv, 2008
The period of a curve is the smallest positive degree of Galois-invariant divisor classes. The index is the smallest positive degree of rational divisors. We construct examples of genus one curves with prescribed period and index over certain number fields.

Infinite family of elliptic curves of rank at least 4 [PDF]

open access: yesarXiv, 2009
We investigate $\mathbb{Q}$-ranks of the elliptic curve $E_t$: $y^2+txy=x^3+tx^2-x+1$ where $t$ is a rational parameter. We prove that for infinitely many values of $t$ the rank of $E_t(\mathbb{Q})$ is at least 4.
