Clustering coefficient without degree correlations biases
Sara Nadiv Soffer, Alexei Vazquez
The clustering coefficient quantifies how well connected are the neighbors of a vertex in a graph. In real networks it decreases with the vertex degree, which has been taken as a s…
A statistical approach to the traceroute-like exploration of networks: theory and simulations
Luca Dall'Asta, Ignacio Alvarez-Hamelin, Alain Barrat +2
Mapping the Internet generally consists in sampling the network from a limited set of sources by using "traceroute"-like probes. This methodology, akin to the merging of different…
Distance-d covering problems in scale-free networks with degree correlations
Pablo Echenique, Jesus Gomez-Gardenes, Yamir Moreno +1
A number of problems in communication systems demand the distributed allocation of network resources in order to provide better services, sampling and distribution methods. The sol…
Statistics of citation networks
Alexei Vazquez
The out-degree distribution of citation networks is investigated. Statistical data of the number of papers cited within a paper (out-degree) for different journals in the period 19…
Knowing a network by walking on it: emergence of scaling
Alexei Vazquez
A model for growing networks is introduced, having as a main ingredient that new nodes are attached to the network through one existing node and then explore the network through th…
Numerical simulations of directed sandpile models
Alexei Vazquez
Directed sandpile models with different toppling rules are studied by means of numerical simulations in two dimensions, with the purpose of determining the different universality c…
