Zhizhong Huang, Nicolas de SaxcÃ©

Given a flag variety $X$ defined over $Q$ and a point $x$ in $X (R)$ , we study approximations to $x$ by points $v$ in $X (Q)$ , and show that, with an appro…

Effective equidistribution, arithmetic purity of strong approximation, and geometric sieve for affine quadrics

Yang Cao, Zhizhong Huang, Runlin Zhang

Let $k$ be a number field. Let $q (x_{1}, \dots, x_{n})$ be a non-degenerate integral quadratic form in $n \geq 3$ variables with coefficients in $k$ and $m \in k^{\times}$ . Let $X$ be the a…
