摘要:

本文给出了具有有限个旋转群且满足开集条件的迭代函数系统生成的自相似集的可见部分的Assouad维数的上界.该界对所有可见部分都有效,它依赖于集合的可穿透部分,这是本文定义的一个概念。作为一个推论,我们得到在平面的情况下,如果投影是一个有限的或可数的区间联盟,然后可见的部分是1维的。我们还证明了一个可见的部分的Assouad维数是严格小于豪斯多夫维数的集合提供的投影包含内点。

英文摘要:

We derive an upper bound for the Assouad dimension of visible parts of self-similar sets generated by iterated function systems with finite rotation groups and satisfying the open set condition. The bound is valid for all visible parts and it depends on the penetrable part of the set, which is a concept defined in this paper. As a corollary, we obtain in the planar case that if the projection is a finite or countable union of intervals then the visible part is 1-dimensional. We also prove that the Assouad dimension of a visible part is strictly smaller than the Hausdorff dimension of the set provided the projection contains interior points.
