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...

When we study the architecture of networks of spatially extended systems the nodes in the network are subject to local … correlation structures. In this case, we show that for scale-free networks the traditional way to estimate the clustering …

The extraction of relevant and meaningful information from large streams of data has become one of the major challenges for scientists working in the field of complex systems. In particular, one of the main goals is to get information about the underlying system of interactions that leads to...

We explore a novel method to generate and characterize complex networks by means of their embedding on hyperbolic … surfaces. Evolution through local elementary moves allows the exploration of the ensemble of networks which share common …

-to-all (ATA) networks, the system undergoes a phase transition at a critical value of Kc=1. Scale-free networks were also found to … network. At criticality, the time to consensus for sparse networks with broad degree distributions (e.g., scale-free networks …) approaches that of the ATA networks, although somewhat more cooperation (higher Kc) is required. …

Queueing theory has been recently proposed as a framework to model the heavy tailed statistics of human activity patterns. The main predictions are the existence of a power-law distribution for the interevent time of human actions and two decay exponents α=1 and α=3/2. Current models lack,...

Agents are represented by nodes on a random graph (e.g., “small world”). Each agent is endowed with a zero-mean random value that may be either positive or negative. All agents attempt to find relief, i.e., to reduce the magnitude of that initial value, to zero if possible, through...
