F_q(T)上具有小导体的强Weil曲线

Strong Weil curves over F_q(T) with small conductor

Andreas Schweizer

摘要:

我们继续工作的Gekeler和其他椭圆曲线上的${\mathbb F}_q(T)$与导体$\infty\cdot{\mathfrak n}$其中${\mathfrak n}\in{\mathbb F}_q[T]$的程度3。由于Frobenius issues有无限多的曲线在每个issues类,我们讨论特别是这些曲线是强Weil曲线相对于均匀化的Drinfeld模曲线$X_0({\mathfrak n})$。作为推论,我们得到强Weil曲线$E/{\mathbb F}_q(T)$总是给出$\bar{{\mathbb F}_q}$上的有理椭圆曲面.

英文摘要:

We continue work of Gekeler and others on elliptic curves over ${\mathbb F}_q(T)$ with conductor $\infty\cdot{\mathfrak n}$ where ${\mathfrak n}\in{\mathbb F}_q[T]$ has degree 3. Because of the Frobenius isogeny there are infinitely many curves in each isogeny class, and we discuss in particular which of these curves is the strong Weil curve with respect to the uniformization by the Drinfeld modular curve $X_0({\mathfrak n})$. As a corollary we obtain that the strong Weil curve $E/{\mathbb F}_q(T)$ always gives a rational elliptic surface over $\bar{{\mathbb F}_q}$.
