Weak approximation for Campana points on projective spaces

Dasheng Wei

We prove weak approximation for Campana points on the projective line with log Fano boundary, and on projective $n$ -space with either $n + 3$ hyperplanes in general position or two t…

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…
