初等阻塞与Weil限制
The elementary obstruction and the Weil restriction
摘要：
在这篇文章中，我们调查的良好行为的基本障碍，介绍了Colliot-Thelene和Santiago。这是对某些代数簇上存在一个有理点的一种阻碍。在Picard群上假设一些条件，我们证明了初等阻塞在簇的Weil限制下表现良好。
英文摘要：
In this text we investigate the good behaviour of the elementary obstruction, introduced by Colliot-Thelene and Sansuc. This is an obstruction to the existence of a rational points on certain algebraic varieties. Assuming some conditions on the Picard group, we prove that the elementary obstruction behaves well under the Weil restriction of a variety.
