椭圆曲线扭曲L值的积分性

Integrality of twisted L-values of elliptic curves

Hanneke Wiersema, Christian Wuthrich

摘要:

在适当的,相当弱的假设下,椭圆曲线$E/\mathbb{Q}$和一个原始的非平凡的Dirichlet字符$χ$,我们证明了代数$L$ -值$\mathscr{L}(E,χ)$在$s=1$是一个代数整数。例如,对于半稳定曲线,只要$E$不允许在$\mathbb{Q}$上定义同构,则$\mathscr{L}(E,χ)$是整数。此外,我们给出的例子说明,我们的假设是必要的完整性举行。

英文摘要:

Under suitable, fairly weak hypotheses on an elliptic curve $E/\mathbb{Q}$ and a primitive non-trivial Dirichlet character $χ$, we show that the algebraic $L$-value $\mathscr{L}(E,χ)$ at $s=1$ is an algebraic integer. For instance, for semistable curves $\mathscr{L}(E,χ)$ is integral whenever $E$ admits no isogenies defined over $\mathbb{Q}$. Moreover we give examples illustrating that our hypotheses are necessary for integrality to hold.
