临界$L$ -Gross曲线值

Critical $L$-values of Gross curves

Andrzej Dąbrowski, Tomasz Jędrzejak, Lucjan Szymaszkiewicz

摘要:

设$K = \mathbb Q(\sqrt{-q})$,其中$q$是$3$模$4$的素同余。令$A = A(q)$表示$K$的Hilbert类域$H$上的Gross曲线。在本注记中,我们使用Magma来计算所有这样的$q$的值$L(E/H, 1)$,直到所有素数$q$与$7$模$8$全等的合理范围。所有这些值都是非零的,并且使用Birch和Swinnerton-Dyer猜想,我们可以计算$A$的Tate-Shafarevich群的假设阶,对于所有这样的$q$直到$4831$。

英文摘要:

Let $K = \mathbb Q(\sqrt{-q})$, where $q$ is a prime congruent to $3$ modulo $4$. Let $A = A(q)$ denote the Gross curve over the Hilbert class field $H$ of $K$. In this note we use Magma to calculate the values $L(E/H, 1)$ for all such $q$'s up to some reasonable ranges for all primes $q$ congruent to $7$ modulo $8$. All these values are non-zero, and using the Birch and Swinnerton-Dyer conjecture, we can calculate hypothetical orders of the Tate-Shafarevich group of $A$ for all such $q$ up to $4831$.
