Geometric correlations mitigate the extreme vulnerability of multiplex networks against targeted attacks
Kaj-Kolja Kleineberg, Lubos Buzna, Fragkiskos Papadopoulos +2
We show that real multiplex networks are unexpectedly robust against targeted attacks on high degree nodes, and that hidden interlayer geometric correlations predict this robustnes…
Controlling congestion on complex networks: fairness, efficiency and network structure
Lubos Buzna, Rui Carvalho
We consider two elementary (max-flow and uniform-flow) and two realistic (max-min fairness and proportional fairness) congestion control schemes, and analyse how the algorithms and…
Resilience of natural gas networks during conflicts, crises and disruptions
Rui Carvalho, Lubos Buzna, Flavio Bono +3
Human conflict, geopolitical crises, terrorist attacks, and natural disasters can turn large parts of energy distribution networks offline. Europe's current gas supply network is l…
Role of Network Topology in the Synchronization of Power Systems
Sergi Lozano, Lubos Buzna, Albert Díaz-Guilera
We study synchronization dynamics in networks of coupled oscillators with bimodal distribution of natural frequencies. This setup can be interpreted as a simple model of frequency…
Fair sharing of resources in a supply network with constraints
Rui Carvalho, Lubos Buzna, Wolfram Just +2
This paper investigates the effect of network topology on the fair allocation of network resources among a set of agents, an all-important issue for the efficiency of transportatio…
Decelerated spreading in degree-correlated networks
Markus Schläpfer, Lubos Buzna
While degree correlations are known to play a crucial role for spreading phenomena in networks, their impact on the propagation speed has hardly been understood. Here we investigat…
