Fourth International Symposium
Engineering of Chemical Complexity
Berlin, June 7-9, 2006
Program and Organization: G. Ertl, A. S. Mikhailov, H. H. Rotermund
The aim of this meeting is to review current perspectives for design, manipulation and efficient control of self-organizing complex chemical systems, ranging from biotechnology and reactive nanostructures to macroscopic pattern formation in chemical reactors. Both experimental studies of such phenomena and their mathematical modeling will be discussed. Possible technological applications of self-organization phenomena shall be considered.

Collective behavior in addressable excitable media
Abstract:
We discuss two topics of collective behavior in the context of excitable media models, swarming
behavior and spatiotemporal networks. Studies of stabilized reaction-diffusion waves and their
interactions are described. We also describe studies of dynamical networks in which nonlocal
excitations occur by nondiffusive jumps along shortcuts defined in the medium.
