解析秩为零时的可见性与Birch和Swinnerton-Dyer猜想

Visibility and the Birch and Swinnerton-Dyer conjecture for analytic rank zero

Amod Agashe

摘要:

令$E$是具有解析秩零的导体$N$的$\Q$上的最优椭圆曲线,即,使得$E$的$L$函数$L_E(s)$在$s=1$处不消失。假设在同一导体$N$的$\Q$上存在另一个最优椭圆曲线,其Mordell-Weil秩大于零,并且其相关联的新形式与$E$以整数$r$为模的相关联的新形式全等。可见性理论则表明,在某些附加的假设下,$r$划分$E$的Shafarevich-Tate群的阶数与$E$的算术分量群的阶数的乘积。我们从Birch和Swinnerton-Dyer的乘积的代数公式中提取出一个显式的整数因子,并在类似于上述情形的假设下,证明了$r$能整除这个整数因子.这为Birch和Swinnerton-Dyer猜想的第二部分在解析秩为零的情况下提供了理论证据。

英文摘要:

Let $E$ be an optimal elliptic curve over $\Q$ of conductor $N$ having analytic rank zero, i.e., such that the $L$-function $L_E(s)$ of $E$ does not vanish at $s=1$. Suppose there is another optimal elliptic curve over $\Q$ of the same conductor $N$ whose Mordell-Weil rank is greater than zero and whose associated newform is congruent to the newform associated to $E$ modulo an integer $r$. The theory of visibility then shows that under certain additional hypotheses, $r$ divides the product of the order of the Shafarevich-Tate group of $E$ and the orders of the arithmetic component groups of $E$. We extract an explicit integer factor from the the Birch and Swinnerton-Dyer conjectural formula for the product mentioned above, and under some hypotheses similar to the ones made in the situation above, we show that $r$ divides this integer factor. This provides theoretical evidence for the second part of the Birch and Swinnerton-Dyer conjecture in the analytic rank zero case.
