Birch和Swinnerton-Dyer猜想著名地预言椭圆曲线的秩可以从它的L-函数计算。在这篇文章中,我们考虑了这个猜想的一个较弱的版本,称为奇偶猜想,并证明了以下内容。设E1和E2是定义在数域K上的两条椭圆曲线,其2-挠群同构为Galois模。假设E1和E2的Shafarevich-Tate群是有限的,我们证明了Birch和Swinnerton-Dyer猜想正确地预言了E1×E2的秩的奇偶性。利用这个结果,我们完成了全真实的域上椭圆曲线p-奇偶猜想的证明。
The Birch and Swinnerton–Dyer conjecture famously predicts that the rank of an elliptic curve can be computed from its L-function. In this article, we consider a weaker version of this conjecture called the parity conjecture and prove the following. Let E1 and E2 be two elliptic curves defined over a number field K whose 2-torsion groups are isomorphic as Galois modules. Assuming finiteness of the Shafarevich–Tate groups of E1 and E2, we show that the Birch and Swinnerton-Dyer conjecture correctly predicts the parity of the rank of E1×E2. Using this result, we complete the proof of the p-parity conjecture for elliptic curves over totally real fields.
