Analysis of a maximum-entropy based estimator for dynamic random graph models
Diego Garlaschelli, Michel Mandjes, Frank P. Pijpers +1
We study dynamic random graphs in which the set of nodes is fixed, but edges evolve over time according to an underlying stochastic mechanism. Using a maximum-entropy approach, we…
Hyperscaling of spatial fluctuations constrains the development of urban populations
Wout Merbis, Fernando A. N. Santos, Jay Armas +2
Urban populations exhibit fractal organization and systematic scaling regularities, yet the scaling exponents reported across cities vary substantially, challenging existing theory…
The effect of a toroidal opinion space on opinion bi-polarisation
Frank P. Pijpers, Benedikt V. Meylahn, Michel R. H. Mandjes
Many models of opinion dynamics include measures of distance between opinions. Such models are susceptible to boundary effects where the choice of the topology of the opinion space…
Critical fragility in socio-technical systems
José Moran, Frank P. Pijpers, Utz Weitzel +2
Socio-technical systems, where technological and human elements interact in a goal-oriented manner, provide important functional support to our societies. Here we draw attention to…
