关于任意凸集的广义Delaunay图是平面图

Generalized Delaunay Graphs with respect to any Convex Set are Plane Graphs

Deniz Sarioz

摘要:

我们考虑了基于平面集C的平面上点集上的两类几何图:一类是由C的平移得到的,另一类是由C的正标度平移(同素异形)得到的。对于紧凸C,由C的缩放平移定义的图,即,基于C的Delaunay图是平面图。我们证明了只要C是凸的,这两类图都是平面图。

英文摘要:

We consider two types of geometric graphs on point sets on the plane based on a plane set C: one obtained by translates of C, another by positively scaled translates (homothets) of C. For compact and convex C, graphs defined by scaled translates of C, i.e., Delaunay graphs based on C, are known to be plane graphs. We show that as long as C is convex, both types of graphs are plane graphs.
