The Price-Pareto growth model of networks with community structure
Łukasz Brzozowski, Marek Gagolewski, Grzegorz Siudem +1
We introduce a new analytical framework for modelling degree sequences in individual communities of real-world networks, e.g., citations to papers in different fields. Our work is…
Gini-stable Lorenz curves and their relation to the generalised Pareto distribution
Lucio Bertoli-Barsotti, Marek Gagolewski, Grzegorz Siudem +1
We introduce an iterative discrete information production process where we can extend ordered normalised vectors by new elements based on a simple affine transformation, while pres…
Equivalence of inequality indices in the three-dimensional model of informetric impact
Lucio Bertoli-Barsotti, Marek Gagolewski, Grzegorz Siudem +1
Inequality is an inherent part of our lives: we see it in the distribution of incomes, talents, citations, to name a few. However, its intensity varies across environments: there a…
Power Laws, the Price Model, and the Pareto type-2 Distribution
Grzegorz Siudem, Przemysław Nowak, Marek Gagolewski
We consider a version of D. Price's model for the growth of a bibliographic network, where in each iteration a constant number of citations is randomly allocated according to a wei…
Modelling railway delay propagation as diffusion-like spreading
Mark M. Dekker, Alexey N. Medvedev, Jan Rombouts +2
Railway systems form an important means of transport across the world. However, congestions or disruptions may significantly decrease these systems' efficiencies, making predicting…
Agent-based model for the h-index - Exact solution
Barbara Żogała-Siudem, Grzegorz Siudem, Anna Cena +1
The Hirsch's -index is perhaps the most popular citation-based measure of the scientific excellence. In 2013 G. Ionescu and B. Chopard proposed an agent-based model for this ind…
Analytical approach to model of scientific revolutions
Paweł Kondratiuk, Grzegorz Siudem, Janusz A. Hołyst
The model of scientific paradigms spreading throughout the community of agents with memory is analyzed using the master equation. The case of two competing ideas is considered for…
External bias in the model of isolation of communities
Julian Sienkiewicz, Grzegorz Siudem, Janusz A. Holyst
We extend a model of community isolation in the d-dimensional lattice onto the case with an imposed imbalance between birth rates of competing communities. We give analytical and n…
