Compatibility of weak approximation for zero-cycles on products of varieties
Yongqi Liang
Zero-cycles are conjectured to satisfy weak approximation with Brauer-Manin obstruction for proper smooth varieties defined over number fields. Roughly speaking, we prove that the…

Non-invariance of weak approximation properties under extension of the ground field
Yongqi Liang
For rational points on algebraic varieties defined over a number field , we study the behavior of the property of weak approximation with Brauer-Manin obstruction under extensio…
