摘要：In this talk we prove two unboundedness results about the Tate-Shafarevich groups of abelian varieties in a fixed nontrivial cyclic extension L/K of global fields, firstly in the case that K is a number field and the abelian varieties are elliptic curves, secondly in the case that K is a global field, [L : K] is a 2-power and the abelian varieties are principally polarized. This is a joint work with Jianfeng Xie.
