题目：Relative version of weak approximation for abelian schemes

摘要：Over number field, weak approximation for algebraic varieties is about the density of rational points in adelic points. In this talk, for an abelian scheme over a rational variety, instead of considering the weak approximation, we consider the relative closed subgroup generated by rational points in adelic points of the total space, and study its relation with cohomological obstruction.
