圆周旋转中的重

Heaviness in Circle Rotations

David Ralston

摘要:

我们关心的是描述结构的一组点在单位区间,当受到旋转的无理α模1,为所有有限部分的轨道包含至少一样多的点在下半部分的间隔,因为在上半部分。具体来说,一个归纳程序描述的基础上的连分数扩展的α集的开发,导致讨论的豪斯多夫维数这一套。取决于参数α,可以实现所有可能的维度,并且该维度的基本下确界(相对于α)是正的。

英文摘要:

We are concerned with describing the structure of the set of points in the unit interval which, when subjected to rotation by irrational alpha modulo one, for all finite portions of the orbit contain at least as many points in the bottom half of the interval as in the top half. Specifically, an inductive procedure for describing the set based on the continued fraction expansion of alpha is developed, leading into a discussion of the Hausdorff dimension of this set. Depending on the parameter alpha, all possible dimensions may be achieved, and the essential infimum (with respect to alpha) of this dimension is positive.
