Self-organisation refers to the ability of systems made of a large number of independent agents inter- acting through local rules to generate large-scale spatio-temporal coherent structures. The emergent properties of interacting agents span systems and scales, from cells forming biological tissues, fish schools moving in synchrony, animal migrations across continents, to robot swarms. By bringing together analysts, mathematical biologists and robotics researchers, this workshop will provide a broad overview of the various self-organization mechanisms that prevail at the various scales and the mathematical models by which they can be described.
