本文研究了由Colliot-Thelene和Sansuc提出的基本障碍的良好行为。这对某些代数簇上有理点的存在性是一个障碍。假设Picard群上的一些条件,我们证明了初等阻塞在一个变量的Weil限制下是很好的。

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.
