球面的可测色数

Measurable Chromatic Number of Spheres

Greg Malen

摘要:

我们研究了可测的色数的距离着色的表面上的2维领域的不同半径,特别显示,类似的参数,用于提高下界在平面上的工作,但一个可数集的半径。此外,我们表明,可测的色数作为半径的函数,或更一般的曲率,是不是单调的。

英文摘要:

We examine the measurable chromatic number of distance colorings on the surface of 2-dimensional spheres of varying radii, showing in particular that similar arguments to those used to raise lower bounds in the plane work for all but a countable set of radii. Furthermore, we show that measurable chromatic number as a function of the radius, or more generally the curvature, is not monotonic.
