违反Hasse原理的全局域上的曲线

Curves over global fields violating the Hasse Principle

Pete L. Clark

摘要:

回答B的问题。Poonen,我们展示了每一个全球领域k的代数曲线超过k违反哈塞原则。事实上,我们可以在某些椭圆模曲线的Atkin-Lehner扭曲中找到这样的例子,在正特征中,还有德林费尔德模曲线。我们的主要工具是“扭曲反哈斯原则”(TAHP)的细化。我们还使用TAHP构建进一步的哈塞原则的侵犯,例如曲线之间的任何数字段的任何给定的属g至少是2。

英文摘要:

In response to a question of B. Poonen, we exhibit for each global field k an algebraic curve over k which violates the Hasse Principle. In fact we can find such examples among Atkin-Lehner twists of certain elliptic modular curves and -- in positive characteristic -- Drinfeld modular curves. Our main tool is a refinement of the "Twist Anti-Hasse Principle" (TAHP). We also use TAHP to construct further Hasse Principle violations, for instance among curves over any number field of any given genus g which is at least 2.
