We discuss Chapter 6 from Silverman & Tate’s Rational Points on Elliptic Curves, in which the authors outline a means of proving Kronecker’s Jugendtraum for Q and Q(i). One considers C[n], the kernel of the multiplication-by-n map on an elliptic curve C. After defining the number field Q(C[n]), we examine instances in which its Galois group over a field K is abelian. For the elliptic curve

We discuss abelian variety and use it to generalize the concept of elliptic curve we discussed in the class. We state some of the basic properties of abelian variety and in particular 1-dimensional abelian variety. The main result of this report is to show that elliptic curve is that the only 1-dimensional abelian variety.

Pairing-based cryptosystems have been developing very fast in the last few years. As the key primitive, pairing is also the heaviest operation in these systems. The performance of pairing affects the application of the schemes in practice. In this report, we summarise the formulas of the Tate pairing operation on elliptic curves in different coordinate systems and describe a few observations of...

A large part of modern arithmetic geometry is dedicated to or motivated by the study of rational points on varieties. For an elliptic curve over Q, the set of rational points forms a finitely generated abelian group. The ranks of these groups, when ranging over all elliptic curves, are conjectured to be evenly distributed between rank 0 and rank 1, with higher ranks being negligible. We will de...

If we set y(u) = 1 2℘ (u) and x(u) = ℘(u), then we have an equation y(u) = x(u)+ · · · , that is a defining equation of the elliptic curve to which the fu...

This is an exposition of some of the main features of the theory of elliptic curves and modular forms.

We introduce an elliptic analogue of the Apostol sums, which we call elliptic Apostol sums. These sums are defined by means of certain elliptic functions with a complex parameter τ having positive imaginary part. When τ → i∞, these elliptic Apostol sums represent the well-known Apostol generalized Dedekind sums. Also these elliptic Apostol sums are modular forms in the variable τ . We obtain a ...

We derive a general expression for an interface parameter which makes possible the design of a neutral elliptic inhomogeneity when the stress field in the surrounding matrix is a polynomial function of nth order and the composite is subjected to antiplane shear deformations. © 2005 Elsevier Ltd.

To help motivate the Weil pairing, we discuss it in the context of elliptic curves over the field of complex numbers.
