18 September 2013 - Barcelona, Spain

A satellite workshop of the ECCS 2013: European Conference on Complex Systems

Description

It is generally agreed that complex systems are comprised of a large number of sub-components and their interactions; moreover, they often exhibit different levels and possess structure at different spatial and temporal scales. Consequently, for the understanding of complex systems, the interplay between those levels and scales is fundamental. In some applications, the levels are already given or can be naturally identified, for instance as neurons, brains, individuals, and social organizations, based on which scientific disciplines like neuroscience, psychology, sociology, economy, etc., have evolved. Moreover, even within a single discipline, it is often necessary or desirable to seek and understand multiple levels of description. On the other hand, in many applications natural candidates for levels are not always obvious. In general, understanding the role of levels in complex systems remains a grand challenge and generally applicable tools and methods are scarce. This workshop aims to discuss mathematical methods for the description of complex multi-level systems and their dynamics. Specific topics include

• Structure formation and information flow within and between levels
• Methods for identifying emergent levels
• Coarse graining of patterns and networks
• Dynamical systems on graphs and hypergraphs
• Understanding the level structure and dynamics resulting from aggregation and averaging methods
• Multi-level approaches in application areas
