论文摘要
1976年，西蒙斯（Simmons）猜想，半径二维球的每种着色严格大于$ 1/2 $三种颜色的$ 1/2 $，在距离1的距离上有几个单色点。我们证明了这个猜想。
In 1976 Simmons conjectured that every coloring of a 2-dimensional sphere of radius strictly greater than $1/2$ in three colors has a couple of monochromatic points at the distance 1 apart. We prove this conjecture.
