The convergence evolution in Europe from a complex networks perspective
Papadimitriou, Theophilos; Gkonkas, Periklēs; … - In: Journal of Risk and Financial Management 15 (2022) 10, pp. 1-14
The evolution of the convergence among the European countries, including both Eurozone as well as non-Eurozone economies, is investigated in this paper. To do so, we construct correlation-based networks and study them by employing the Threshold Weighted-Minimum Dominating Set (TW-MDS) algorithm...

Synchronization analysis of delayed complex networks with time-varying couplings
Li, Ping; Yi, Zhang - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 14, pp. 3729-3737
In this paper, a new method is presented to analyze the linear stability of the synchronized state in arbitrarily coupled complex dynamical systems with time delays. The coupling configurations are not restricted to the symmetric and irreducible connections or the non-negative off-diagonal...
