An Infinite Family of Serre Curves
نویسنده
چکیده
Given an elliptic curve E/Q, the torsion points of E give rise to a natural Galois representation ρE : Gal(Q/Q) → GL2(Ẑ) associated to E. In 1972, Serre showed that [GL2(Ẑ) : Im ρE ] ≥ 2 for all non-CM elliptic curves. The main goal of this paper is to exhibit an elliptic surface such that the Galois representations associated to almost all of the rational specializations have maximal image. Further, we find an explicit set S ⊂ Q, such that if t 6∈ S, then the Galois representation associated to the specialization at t has maximal image, with a bounded number of exceptions.

Complete characterization of the Mordell-Weil group of some families of elliptic curves
The Mordell-Weil theorem states that the group of rational points on an elliptic curve over the rational numbers is a finitely generated abelian group. In our previous paper, H. Daghigh, and S. Didari, On the elliptic curves of the form $ y^2=x^3-3px$, Bull. Iranian Math. Soc. 40 (2014), no. 5, 1119--1133., using Selmer groups, we have shown that for a prime $p...
متن کاملOn the Elliptic Curves of the Form $y^2 = x^3 − pqx$
By the Mordell- Weil theorem, the group of rational points on an elliptic curve over a number field is a finitely generated abelian group. This paper studies the rank of the family Epq:y2=x3-pqx of elliptic curves, where p and q are distinct primes. We give infinite families of elliptic curves of the form y2=x3-pqx with rank two, three and four, assuming a conjecture of Schinzel ...
متن کاملElliptic curves with full 2-torsion and maximal adelic Galois representations
In 1972, Serre showed that the adelic Galois representation associated to a non-CM elliptic curve over a number field has open image in GL2(Ẑ). In [Gre10], Greicius develops necessary and sufficient criteria for determining when this representation is actually surjective and exhibits such an example. However, verifying these criteria turns out to be difficult in practice; Greicius describes tes...
متن کاملThe Algebraic Formalism of Soliton Equations over Arbitrary Base Fields
The aim of this paper is to offer an algebraic construction of infinitedimensional Grassmannians and determinant bundles. As an application we construct the τ -function and formal Baker-Akhiezer functions over arbitrary fields, by proving the existence of a “formal geometry” of local curves analogous to the geometry of global algebraic curves. Recently G. Anderson ([A]) has constructed the infi...
متن کاملAn iterative method for amenable semigroup and infinite family of non expansive mappings in Hilbert spaces
begin{abstract} In this paper, we introduce an iterative method for amenable semigroup of non expansive mappings and infinite family of non expansive mappings in the frame work of Hilbert spaces. We prove the strong convergence of the proposed iterative algorithm to the unique solution of a variational inequality, which is the optimality condition for a minimization problem. The results present...
