再论Châtelet曲面丛的算法
Arithmetic of Châtelet surface bundles revisited
摘要：
将Lagrange插值应用于纤维化，研究数域上代数簇的算法。假设某条椭圆曲线的Tate-Shafarevich群是有限的，我们证明了对于曲线上的Châtelet曲面丛，由Brauer-Manin障碍引起的对Hasse原理的违反在基域的任意有限扩张下不是不变的.
英文摘要：
We study arithmetic of the algebraic varieties defined over number fields by applying Lagrange interpolation to fibrations. Assuming the finiteness of the Tate-Shafarevich group of a certain elliptic curve, we show, for Châtelet surface bundles over curves, that the violation of Hasse principle being accounted for by the Brauer-Manin obstruction is not invariant under an arbitrary finite extension of the ground field.
