Abstract

We formulate the basic principles of multi-agents complex system dynamics following the lessons from experimental neuro- and cognitive science: 1) the cognitive dynamics in a changing environment is transient and can be considered as a temporal sequence of metastable states; 2) the available resources for the information processing are limited; 3) the transient dynamics is robust against noise and at the same time sensitive to information signals. We suggest the basic dynamical models that describe the evolution of cooperative modes. We focus on two limit cases: a) the unstable manifold of metastable states has one leading direction and many others that are characterized by small positive eigenvalues (system on the edge of instability), and b) the unstable manifold is characterized by small number of positive eigenvalues having the same range (integration of different flows - binding).
