我们表明，与其拓扑（Voronoi）邻居对齐的自驱动粒子的集体属性与使用度量相互作用范围的常用模型有质的不同。正如最近的观察所表明的那样，在最小设置中显示的这种无度量相互作用的相关性表明，细胞、鸟群和鱼群的内聚运动的现实模型可能必须将它们纳入其中。
We show that the collective properties of self-propelled particles aligning with their topological (Voronoi) neighbors are qualitatively different from those of usual models where metric interaction ranges are used. This relevance of metric-free interactions, shown in a minimal setting, indicate that realistic models for the cohesive motion of cells, bird flocks, and fish schools may have to incorporate them, as suggested by recent observations.
