Weak approximation for homogeneous spaces over some two‐dimensional geometric global fields
Weak approximation for homogeneous spaces over some two‐dimensional geometric global fields
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 C ( ( x , y ) ) $\mathbb {C}((x,y))$ or function fields of curves over C ( ( t ) ) $\mathbb {C}((t))$ . …
