Brauer-Manin阻塞应用于耳郭盖的不足

Insufficiency of the Brauer-Manin obstruction applied to etale covers

Bjorn Poonen

摘要:

设k是特征不为2的全局域。我们构造一个k-簇X,使得X(k)为空,但是对于它,空性不能用Brauer-Manin阻塞来解释,甚至不能用Brauer-Manin阻塞来解释有限的etale覆盖。

英文摘要:

Let k be any global field of characteristic not 2. We construct a k-variety X such that X(k) is empty, but for which the emptiness cannot be explained by the Brauer-Manin obstruction or even by the Brauer-Manin obstruction applied to finite etale covers.
