Reciprocity obstruction to strong approximation over p-adic function fields
Haowen Zhang
Over function fields of p-adic curves, we construct stably rational varieties in the form of homogeneous spaces of SL_n with semisimple simply connected stabilizers and we show tha…

Weak approximation for homogeneous spaces over some two-dimensional geometric global fields
Haowen Zhang
In this article, we study obstructions to weak approximation for connected linear groups and homogeneous spaces with connected or abelian stabilizers over finite extensions of $\ma…
