Entropy distribution and condensation in random networks with a given degree distribution

K Anand, D Krioukov, G Bianconi - Physical Review E, 2014 - APS
The entropy of network ensembles characterizes the amount of information encoded in the
network structure and can be used to quantify network complexity and the relevance of given …

Variational principle for scale-free network motifs

C Stegehuis, R Hofstad, JSH van Leeuwaarden - Scientific reports, 2019 - nature.com
For scale-free networks with degrees following a power law with an exponent τ∈(2, 3), the
structures of motifs (small subgraphs) are not yet well understood. We introduce a method …

Statistical mechanics of random geometric graphs: Geometry-induced first-order phase transition

M Ostilli, G Bianconi - Physical Review E, 2015 - APS
Random geometric graphs (RGGs) can be formalized as hidden-variables models where the
hidden variables are the coordinates of the nodes. Here we develop a general approach to …

Scale-free network clustering in hyperbolic and other random graphs

C Stegehuis, R van Der Hofstad… - Journal of Physics A …, 2019 - iopscience.iop.org
Random graphs with power-law degrees can model scale-free networks as sparse
topologies with strong degree heterogeneity. Mathematical analysis of such random graphs …

Parameter estimators of sparse random intersection graphs with thinned communities

J Karjalainen, JSH van Leeuwaarden… - Algorithms and Models for …, 2018 - Springer

Optimal subgraph structures in scale-free configuration models

R Van der Hofstad, JSH Van Leeuwaarden… - 2021 - projecteuclid.org
Subgraphs reveal information about the geometry and functionalities of complex networks.

Degree correlations in scale-free random graph models

C Stegehuis - Journal of Applied Probability, 2019 - cambridge.org
We study the average nearest-neighbour degree a (k) of vertices with degree k. In many real-
world networks with power-law degree distribution, a (k) falls off with k, a property ascribed …

When is a scale-free graph ultra-small?

R van der Hofstad, J Komjáthy - Journal of Statistical Physics, 2017 - Springer
In this paper we study typical distances in the configuration model, when the degrees have
asymptotically infinite variance. We assume that the empirical degree distribution follows a …

Switch chain mixing times and triangle counts in simple random graphs with given degrees

T Bannink, R van der Hofstad… - Journal of Complex …, 2019 - academic.oup.com
Sampling uniform simple graphs with power-law degree distributions with degree exponent
is a non-trivial problem. Firstly, we propose a method to sample uniform simple graphs that …

Characterizing the intrinsic correlations of scale-free networks

JB De Brito, CIN Sampaio Filho, AA Moreira… - … Journal of Modern …, 2016 - World Scientific
When studying topological or dynamical properties of random scale-free networks, it is tacitly
assumed that degree–degree correlations are not present. However, simple constraints …
