椭圆曲线及数域与函数域的类比

Elliptic curves and analogies between number fields and function fields

Douglas Ulmer

摘要:

数域和函数域之间众所周知的相似性导致了许多问题从一个领域转移到另一个领域。本文将在椭圆曲线理论中讨论这类双向业务。在本文的第一部分,我们考虑各种工作的Heegner点和Gross-Zagier公式的功能领域的背景下,这些工作导致一个完整的证明猜想的伯奇和Swinnerton-Dyer的椭圆曲线的解析秩最多为1的功能领域的特征> 3。在本文的第二部分中,我们将回顾这样一个事实,即秩猜想椭圆曲线的功能领域是现在已知的是真实的,并证明这一点的曲线有渐近最大秩的导体。这些曲线满足秩界的事实表明了一些有趣的问题,椭圆曲线上的数域,分圆域,和功能领域的数域。这些问题在本文的最后四个部分进行了讨论。

英文摘要:

The well-known analogies between number fields and function fields have led to the transposition of many problems from one domain to the other. In this paper, we will discuss traffic of this sort, in both directions, in the theory of elliptic curves. In the first part of the paper, we consider various works on Heegner points and Gross-Zagier formulas in the function field context; these works lead to a complete proof of the conjecture of Birch and Swinnerton-Dyer for elliptic curves of analytic rank at most 1 over function fields of characteristic > 3. In the second part of the paper, we will review the fact that the rank conjecture for elliptic curves over function fields is now known to be true, and that the curves which prove this have asymptotically maximal rank for their conductors. The fact that these curves meet rank bounds suggests a number of interesting problems on elliptic curves over number fields, cyclotomic fields, and function fields over number fields. These problems are discussed in the last four sections of the paper.
