-free networks embedded by the suggested algorithm are studied both analytically and through simulations. Our findings indicate … dramatic changes in the embedded networks, in comparison to their off-lattice counterparts, and call into question the … applicability of off-lattice scale-free models to realistic, everyday-life networks. …

in Erdős–Rényi (ER) and random scale free (SF) networks, with degree distribution P(k)=ck−λ. We show that the chemical … dimension is dl=2 for ER and SF networks with λ>4, as in percolation in d⩾dc=6 dimensions. For 3<λ<4 we show that dl=(λ−2)/(λ−3 …)/(λ−3) (3<λ<4). We discuss the meaning of these dimensions for networks. …

We investigate a model of stratified economic interactions between agents when the notion of spatial location is introduced. The agents are placed on a network with near-neighbor connections. Interactions between neighbors can occur only if the difference in their wealth is less than a threshold...

The generation mechanisms of real world networks have been described using multiple models. The mathematical features … of these models are usually extrapolated from statistical properties of a snapshot of these networks. We here propose an … edges surrounding a newly added edge. The N-node local structure measurements reproduce for some networks the now classical …

We study the Brazilian Popular Music in a network perspective. We call the Brazilian Popular Music Network, BPMN, the graph where the vertices are the song writers and the links are determined by the existence of at least a common singer. The linking degree distribution of such graph shows power...

Detecting overlapping communities is a challenging task in analyzing networks, where nodes may belong to more than one … networks and real-world networks. The experiments show that this method is efficient at detecting overlapping communities and … can provide better performance on the networks where a majority of nodes belong to more than one community. …

Synchronization is a phenomenon observed in all of the living and in much of the non-living world, for example in the heart beat, Huygens’ clocks, the flashing of fireflies and the clapping of audiences. Depending on the number of degrees of freedom involved, different mathematical approaches...
