假设平面上有一组彩色点,其中没有三个点共线,并且每种颜色最多出现在最多点上。我们证明了(如果是偶数)上非交叉正确着色几何完美匹配的存在性,以及最大度数最大的非交叉正确着色几何生成树的存在性。此外,我们证明了平面晶格中非交叉正确着色几何完美匹配的存在。为了证明我们的结果,我们提出了一个有用的引理,它给出了彩色点序列的良好划分。
Letbe a set of multicolored points in the plane such that no three points are collinear and each color appears on at mostpoints. We show the existence of a non-crossing properly colored geometric perfect matching on(ifis even), and the existence of a non-crossing properly colored geometric spanning tree with maximum degree at moston. Moreover, we show the existence of a non-crossing properly colored geometric perfect matching in the plane lattice. In order to prove these our results, we propose an useful lemma that gives a good partition of a sequence of multicolored points.
