Arithmetic purity of strong approximation for toric varieties with constant global sections

Dasheng Wei, Fei Xu, Yi Zhu

Let $X$ be a smooth toric variety over a number field $k$ such that the global sections of $X$ are constant. We show that $U (k)$ is dense in $U (A_{k})^{Br_{1} (U)}$ for…

Strong approximation for the intersection of two quadrics

Dasheng Wei, Jie Xu, Yi Zhu

We study strong approximation for the intersection of two affine quadrics. As its application, we prove the fibration method for weak approximation over number fields of rank four…

The arithmetic puncturing problem and integral points

David McKinnon, Yi Zhu

In this paper, we provide evidence to support a positive answer to a question of Hassett and Tschinkel. In particular, if an algebraic variety V has a dense set of rational points,…
