Systemic risk analysis in reconstructed economic and financial networks
Giulio Cimini, Tiziano Squartini, Diego Garlaschelli +1
We address a fundamental problem that is systematically encountered when modeling complex systems: the limitedness of the information available. In the case of economic and financi…
Multiplexity and multireciprocity in directed multiplexes
Valerio Gemmetto, Tiziano Squartini, Francesco Picciolo +2
Real-world multi-layer networks feature nontrivial dependencies among links of different layers. Here we argue that, if links are directed, dependencies are twofold. Besides the or…
Multiplexity versus correlation: the role of local constraints in real multiplexes
Valerio Gemmetto, Diego Garlaschelli
Several real-world systems can be represented as multi-layer complex networks, i.e. in terms of a superposition of various graphs, each related to a different mode of connection be…
Estimating topological properties of weighted networks from limited information
Giulio Cimini, Tiziano Squartini, Andrea Gabrielli +1
A fundamental problem in studying and modeling economic and financial systems is represented by privacy issues, which put severe limitations on the amount of accessible information…
