多维无理旋转的有界差集

Sets of bounded discrepancy for multi-dimensional irrational rotation

Sigrid Grepstad, Nir Lev

摘要:

研究了$d$维环面关于无理旋转的有界剩余集.这个问题可以追溯到Hecke,Ostrowski和Kesten,他们在一维上刻画了有界剩余的区间。首先通过构造一类$d$ -维有界余项平行六面体,将Hecke-Ostrowski的结果推广到了多维.然后,我们刻画了黎曼可测有界剩余集的“等可分解性”,这样一个平行六面体。通过构造关于这个等分解的不变量,我们得到了一个多面体是有界剩余集的明确条件。特别是这产生了一个特征的凸有界剩余多边形在两个维度。该方法也被用来获得其他几个结果。

英文摘要:

We study bounded remainder sets with respect to an irrational rotation of the $d$-dimensional torus. The subject goes back to Hecke, Ostrowski and Kesten who characterized the intervals with bounded remainder in dimension one. First we extend to several dimensions the Hecke-Ostrowski result by constructing a class of $d$-dimensional parallelepipeds of bounded remainder. Then we characterize the Riemann measurable bounded remainder sets in terms of "equidecomposability" to such a parallelepiped. By constructing invariants with respect to this equidecomposition, we derive explicit conditions for a polytope to be a bounded remainder set. In particular this yields a characterization of the convex bounded remainder polygons in two dimensions. The approach is used to obtain several other results as well.
