Q的完备化的对角逼近

Diagonal approximation in completions of Q

Matthew Palmer

摘要:

在对角丢番图逼近的背景下,证明了丢番图逼近和度量数论中的一些经典结果(即Dirichlet定理和Duffin-Schaeffer定理)的类似结果,即用$\mathbb{Q}$在此空间中的对角嵌入的元素逼近$\mathbb{R} \times \mathbb{Q}_{p_1} \times \cdots \times \mathbb{Q}_{p_r}$的元素.

英文摘要:

We prove analogues of some classical results from Diophantine approximation and metric number theory (namely Dirichlet's theorem and the Duffin--Schaeffer theorem) in the setting of diagonal Diophantine approximation, i.e. approximating elements of $\mathbb{R} \times \mathbb{Q}_{p_1} \times \cdots \times \mathbb{Q}_{p_r}$ by elements of the diagonal embedding of $\mathbb{Q}$ into this space.
