关于椭圆曲线y^2=x(x-p)(x-2)的秩

On the Rank of the Elliptic Curve y^2=x(x-p)(x-2)

Jeffrey Hatley

摘要:

定义在\Q上的椭圆曲线E是一个代数簇,它形成一个生成的阿贝尔群,并且结构定理意味着E = \Z^r + \Z_{tors},对于某个r \geq 0;这个值r被称为E的秩。曲线的秩分类是椭圆曲线研究中的经典问题。本文利用2-下降法计算了两类椭圆曲线的秩,其中E由E:y^2 = x(x-p)(x-2)给出,p,p-2为孪生素数.

英文摘要:

An elliptic curve E defined over \Q is an algebraic variety which forms a finitely generated abelian group, and the structure theorem then implies that E = \Z^r + \Z_{tors} for some r \geq 0; this value r is called the rank of E. It is a classical problem in the study of elliptic curves to classify curves by their rank. In this paper, the author uses the method of 2-descent to calculate the rank of two families of elliptic curves, where E is given by E: y^2 = x(x-p)(x-2) with p, p-2 being twin primes.
