Numerical assessment of the percolation threshold using complement networks
Giacomo Rapisardi, Guido Caldarelli, Giulio Cimini
Models of percolation processes on networks currently assume locally tree-like structures at low densities, and are derived exactly only in the thermodynamic limit. Finite size eff…
The Grand Canonical ensemble of weighted networks
Andrea Gabrielli, Rossana Mastrandrea, Guido Caldarelli +1
The cornerstone of statistical mechanics of complex networks is the idea that the links, and not the nodes, are the effective particles of the system. Here we formulate a mapping b…
Fragility and anomalous susceptibility of weakly interacting networks
Giacomo Rapisardi, Alex Arenas, Guido Caldarelli +1
Percolation is a fundamental concept that brought new understanding on the robustness properties of complex systems. Here we consider percolation on weakly interacting networks, th…
The Statistical Physics of Real-World Networks
Giulio Cimini, Tiziano Squartini, Fabio Saracco +3
In the last 15 years, statistical physics has been a very successful framework to model complex networks. On the theoretical side, this approach has brought novel insights into a v…
Reconstruction methods for networks: the case of economic and financial systems
Tiziano Squartini, Guido Caldarelli, Giulio Cimini +2
When studying social, economic and biological systems, one has often access to only limited information about the structure of the underlying networks. An example of paramount impo…
Network Sensitivity of Systemic Risk
Amanah Ramadiah, Domenico Di Gangi, D. Ruggiero Lo Sardo +6
A growing body of studies on systemic risk in financial markets has emphasized the key importance of taking into consideration the complex interconnections among financial institut…
Multiple structural transitions in interacting networks
Giacomo Rapisardi, Alex Arenas, Guido Caldarelli +1
Many real-world systems can be modeled as interconnected multilayer networks, namely a set of networks interacting with each other. Here we present a perturbative approach to study…
Structural changes in the interbank market across the financial crisis from multiple core-periphery analysis
Sadamori Kojaku, Giulio Cimini, Guido Caldarelli +1
Interbank markets are often characterised in terms of a core-periphery network structure, with a highly interconnected core of banks holding the market together, and a periphery of…
