摘要翻译:
我们证明了嵌入曲面上的图是一种强大而实用的工具,可以生成、表征和模拟具有广泛性质的网络。值得注意的是,拓扑嵌入图的研究是非限制性的,因为任何网络都可以嵌入到具有足够高亏格的曲面上。网络的局部性质受曲面亏格的影响,曲面亏格会引起度分布和聚类系数的显著变化。图的全局性质也受到曲面亏格的强烈影响,曲面亏格限制了图的交织度,使图的标度性质由大世界类(小亏格)变为小和超小世界类(大亏格)。两个基本步骤允许探索所有可嵌入在给定表面上的网络,并自然引入一个工具来开发统计力学描述。在这样一个框架内,我们研究了拓扑嵌入图在高温和低温下的性质,观察了通过冷却系统而形成的越来越规则的结构。我们发现,当拓扑无序量较低时,冷却动力学受到表面亏格的强烈影响,表现为类玻璃冻结跃迁。

英文摘要:
We demonstrate that graphs embedded on surfaces are a powerful and practical tool to generate, characterize and simulate networks with a broad range of properties. Remarkably, the study of topologically embedded graphs is non-restrictive because any network can be embedded on a surface with sufficiently high genus. The local properties of the network are affected by the surface genus which, for example, produces significant changes in the degree distribution and in the clustering coefficient. The global properties of the graph are also strongly affected by the surface genus which is constraining the degree of interwoveness, changing the scaling properties from large-world-kind (small genus) to small- and ultra-small-world-kind (large genus). Two elementary moves allow the exploration of all networks embeddable on a given surface and naturally introduce a tool to develop a statistical mechanics description. Within such a framework, we study the properties of topologically-embedded graphs at high and low `temperatures' observing the formation of increasingly regular structures by cooling the system. We show that the cooling dynamics is strongly affected by the surface genus with the manifestation of a glassy-like freezing transitions occurring when the amount of topological disorder is low.
