单位正方形上数量均匀分布的研究

A study in quantitative equidistribution on the unit square

Max Goering, Christian Weiss

摘要:

单位正方形上平移流的分布性质在不同的数学领域都有研究,包括代数几何和差异理论。量化均匀分布的一种方法是比较转换流在特定集合$E \subset [0,1]^2$中花费的实际时间与预期时间之间的误差。本文证明了当$E$在凸集生成的代数中时,对除可数个方向外的所有方向,误差至多为$\log(T)^{1+\varepsilon}$阶.只要方向是不好的近似边界可以锐化为$\log(T)^{1/2+\varepsilon}$。我们产生的误差估计是小于一般的可测集的Beck证明,而我们的类的例子是大于在工作的Grepstad-Larcher谁获得了有界剩余财产为他们的集合。我们的证明依赖于局部凸性的边界和规则性的部分流之间的对偶性。

英文摘要:

The distributional properties of the translation flow on the unit square have been considered in different fields of mathematics, including algebraic geometry and discrepancy theory. One method to quantify equidistribution is to compare the error between the actual time the translation flow spent in specific sets $E \subset [0,1]^2$ to the expected time. In this article, we prove that when $E$ is in the algebra generated by convex sets the error is of order at most $\log(T)^{1+\varepsilon}$ for all but countably many directions. Whenever the direction is badly approximable the bound can be sharpened to $\log(T)^{1/2+\varepsilon}$. The error estimates we produce are smaller than for general measurable sets as proved by Beck, while our class of examples is larger than in the work of Grepstad-Larcher who obtained the bounded remainder property for their sets. Our proof relies on the duality between local convexity of the boundary and regularity of sections of the flow.
