关于平点集上$c\geq 4$类的$U$ -多项式的存在性

On the Existence of $U$-Polygons of Class $c\geq 4$ in Planar Point Sets

Christian Huck

摘要:

对于欧几里德平面中的有限集$U$,凸非退化多边形$P$称为$U$ -多边形,如果平行于$U$的一个方向且与$P$的一个顶点相交的每条线也与$P$的另一个顶点相交。我们刻画了所有顶点都在平面的某些子集上的$c\geq4$类$U$ -多边形的边数,并在分圆模型集的情况下得到了明确的结果。

英文摘要:

For a finite set $U$ of directions in the Euclidean plane, a convex non-degenerate polygon $P$ is called a $U$-polygon if every line parallel to a direction of $U$ that meets a vertex of $P$ also meets another vertex of $P$. We characterize the numbers of edges of $U$-polygons of class $c\geq4$ with all their vertices in certain subsets of the plane and derive explicit results in the case of cyclotomic model sets.
