| Research Abstract |
The present study aims at elucidating how large populations of coupled oscillators change their behaviors (in particular, synchronization and chaos), as some of its elements somehow turn inactive (non self-oscillatory), which process is here referred to as "aging". This problem is important, e.g. in assessing the robustness of machines based on coupled oscillators and generators of diverse biological rhythms such as body clocks against defects or deterioration. This study has shown using mathematical models of coupled oscillators that such a system can exhibit a wide variety of behaviors depending on parameters and its coupling architecture.
