Outline of Final Research Achievements

When components of networks, which show dynamical behavior, are partially damaged, how does the network function maintain and how can it be recovered? It is theoretically and practically important to understand dynamical robustness and dynamical resilience for these networks. In this study, we have analyzed dynamical robustness and resilience of networks which are composed of various types of oscillators and network structures. This analysis gives us wide and deep understanding of dynamical robustness and resilience of correlated networks and coupled-excitable-phase-oscillators networks. In addition, we show fundamental study to apply these understandings into wide fields.
