丢番图逼近的常指数与一致指数之比的最佳界

An optimal bound for the ratio between ordinary and uniform exponents of Diophantine approximation

Antoine Marnat, Nikolay Moshchevitin

摘要:

本文给出了任意维上同时丢番图逼近和线性型的丢番图逼近的平凡指数和一致指数之比的一个下界.这个下界由Schmidt和Summerer证明,并且已经在维度$2$和$3$中示出。这个下界是在参数数的几何的背景下提出的规则系统中达到的,因此是最优的。

英文摘要:

We provide a lower bound for the ratio between the ordinary and uniform exponent of both simultaneous Diophantine approximation and Diophantine approximation by linear forms in any dimension. This lower bound was conjectured by Schmidt and Summerer and already shown in dimension $2$ and $3$. This lower bound is reached at regular systems presented in the context of parametric geometry of numbers, and thus optimal.
