The splitting of primes in division fields of elliptic curves.
We will show the utility of the classical Jacobi Thetanullwerte for the description of certain period lattices of elliptic curves, providing equations with good arithmetical properties. These equations will be the starting point for the construction of families of elliptic curves with everywhere good reduction.[Proceedings of the Primeras Jornadas de Teoría de Números (Vilanova i la Geltrú (Barcelona), 30 June - 2 July 2005)].
Let be a number field, and let be an abelian variety. Let denote the product of the Tamagawa numbers of , and let denote the finite torsion subgroup of . The quotient is a factor appearing in the leading term of the -function of in the conjecture of Birch and Swinnerton-Dyer. We investigate in this article possible cancellations in this ratio. Precise results are obtained for elliptic curves over or quadratic extensions , and for abelian surfaces . The smallest possible ratio...
On donne la liste (à un élément près) des nombres premiers qui sont l’ordre d’un point de torsion d’une courbe elliptique sur un corps de nombres de degré trois.
It is proved that for every k there exist k triples of positive integers with the same sum and the same product.
In this paper we investigate Hesse’s elliptic curves , and construct their twists, over quadratic fields, and over the Galois closures of cubic fields. We also show that is a twist of over the related cubic field when the quadratic field is contained in the Galois closure of the cubic field. We utilize a cubic polynomial, , to parametrize all of quadratic fields and cubic ones. It should be noted that is a twist of as algebraic curves because it may not always have any rational points...
