高秩椭圆曲面和曲线三讲

Three lectures on elliptic surfaces and curves of high rank

Noam D. Elkies

摘要:

在过去的两年中,我们已经改进了几个(Mordell-Weil)秩记录的椭圆曲线在Q和非常数椭圆曲线在Q(t)。例如,我们发现了曲线E/Q在E(Q)中有28个独立点P_i的第一个例子(之前的记录是24,由R.Martin和W.McMillen在2000年发现),以及Q上的曲线的第一个例子,其Mordell-Weil群同构于(Z/2 Z)x Z ^[18](之前的曲线的秩记录是15,由Dujella在2002年发现)。在这些讲座中,我们给出了导致这些新记录和相关应用的一些背景、理论和计算工具。一.背景和概述:定理的Mordell(-Weil)和Mazur;秩问题;的方法Neron-Shioda和梅斯特;椭圆曲面和Neron专业化;领域以外的Q。II椭圆曲面和K3曲面:Mordell-Weil和Neron-Severi群;高Neron-Severi秩的K3曲面及其模; Mordell-Weil秩为17的Q上的椭圆K3曲面。高秩K_3曲面及其模的其他应用III计算问题、技术和结果:Niemeier格的切片;寻找和转换高阶K3曲面的模型;寻找良好的专业化。椭圆曲线的新秩记录摘要。

英文摘要:

Over the past two years we have improved several of the (Mordell-Weil) rank records for elliptic curves over Q and nonconstant elliptic curves over Q(t). For example, we found the first example of a curve E/Q with 28 independent points P_i in E(Q) (the previous record was 24, by R.Martin and W.McMillen 2000), and the first example of a curve over Q with Mordell-Weil group isomorphic with (Z/2Z) x Z^18 (the previous rank record for a curve with a 2-torsion point was 15, by Dujella 2002). In these lectures we give some of the background, theory, and computational tools that led to these new records and related applications. I Context and overview: the theorems of Mordell(-Weil) and Mazur; the rank problem; the approaches of Neron--Shioda and Mestre; elliptic surfaces and Neron specialization; fields other than Q. II Elliptic surfaces and K3 surfaces: the Mordell-Weil and Neron-Severi groups; K3 surfaces of high Neron-Severi rank and their moduli; an elliptic K3 surface over Q of Mordell-Weil rank 17. Some other applications of K3 surfaces of high rank and their moduli. III Computational issues, techniques, and results: slices of Niemeier lattices; finding and transforming models of K3 surfaces of high rank; searching for good specializations. Summary of new rank records for elliptic curves.
