摘要：In this talk, I will begin with a classic example to show some basic idea of the topic. Then I will talk about approximation in semi-simple simply connected groups over some fucntion fields of curves. Finally, I will introduce some arithmetic dualities and their applications in weak approximation for reductive groups over p-adic function fields.
