Self-similar disk packings as model spatial scale-free networksJonathan P. K. Doye and Claire P. MassenPhys. Rev. E 71, 016128 (2005)AbstractThe network of contacts in space-filling disk packings, such as the Apollonian packing, are examined. These networks provide an interesting example of spatial scale-free networks, where the topology reflects the broad distribution of disk areas. A wide variety of topological and spatial properties of these systems are characterized. Their potential as models for networks of connected minima on energy landscapes is discussed.The full paper is available from Physical Review E Online and arXiv.org. |
