Strong approximation for certain quadric fibrations with compact fibers
Fei Xu
In this paper, we will show that strong approximation with Brauer-Manin obstruction holds for certain quadratic fibration such that none of fibers satisfies strong approximation wi…

Very strong approximation for certain algebraic varieties
Qing Liu, Fei Xu
Let F be a global field. In this work, we show that the Brauer-Manin condition on adelic points for subvarieties of a torus T over F cuts out exactly the rational points, if either…
