半平面的Apollonian圆填充

Apollonian circle packings of the half-plane

Michael Ching, John R. Doyle

摘要:

我们考虑半欧几里德平面上的Apollonian圆填充。我们给出了两个这样的包装的充要条件相关的欧氏相似性(即,通过平移,反射,旋转和膨胀),并明确描述了一个给定的包装的自相似性组。我们观察到,包装与非平凡的自相似性对应的正实数的根的二次多项式的合理系数。这反映在阿波罗圆填料和连分数之间的密切联系,使我们能够完全分类这种包装的相似性。

英文摘要:

We consider Apollonian circle packings of a half Euclidean plane. We give necessary and sufficient conditions for two such packings to be related by a Euclidean similarity (that is, by translations, reflections, rotations and dilations) and describe explicitly the group of self-similarities of a given packing. We observe that packings with a non-trivial self-similarity correspond to positive real numbers that are the roots of quadratic polynomials with rational coefficients. This is reflected in a close connection between Apollonian circle packings and continued fractions which allows us to completely classify such packings up to similarity.
