| Research Abstract |
Many real-world complex systems investigated in engineering, biology, and the social sciences can be regarded as dynamical networks of active elements in which the coupling connections and the states of the elements evolve simultaneously. We have first studied an evolving recurrent network in which phase oscillators and synaptic weights interact with each other. We found that the system exhibits three states: two-cluster, coherent with a fixed phase relation, chaotic states with frustration. We believe that, because of its structural stability, our model will provide a framework for describing essential behavior in co-evolving systems.
