Please distribute to others who may be interested... You are hereby invited to a seminar in our tenth interdisciplinary series on Evolution, Complexity and Cognition <http://ecco.vub.ac.be/?q=node/108> (ECCO 2013-2014)
Time: Friday Apr. 18, 14h-16h Place: *room D.1.08 (other than usual!)* ------------------------------ *From networks to hypernetworks in complex systems science* Jeffrey Johnson <http://www.complexityanddesign.org/> (Open University, UK) Abstract: Complex systems have multilevel dynamics emerging from interactions between their parts. Networks have provided deep insights into those dynamics, but only represent relations between *two* things while the generality is relations between *many* things. Hypergraphs and their related Galois connections have long been used to model such relations, but their set theoretic nature has inadequate and inappropriate structure. Simplicial complexes can better represent relations between many things but they too have limitations. *Hypersimplices*, which are defined as simplices in which the relational structure is explicit, overcome these limitations. Hypernetworks, which in the simplest cases are sets of hypersimplices, have a multidimensional connectivity structure which constrains those dynamics represented by patterns of numbers over the hypersimplices and their vertices. The dynamics of hypernetwork also involve the formation and disintegration of hypersimplices, which are seen as structural events related to system time. Hypernetworks provide algebraic structure able to represent multilevel systems and combine their top-down and bottom-up micro, meso and macro-dynamics. Hypernetworks naturally generalise graphs, hypergraphs and networks. These ideas will be presented in a graphical way through examples which also show the relevance of hypernetworks to policy. It will be argued that hypernetworks are necessary if not sufficient for a science of complex systems and its applications. The talk will be aimed at a general audience and no prior knowledge will be assumed. ------------------------------ Upcoming Seminars *Apr. 25 * Safwat Ibrahim *Crowdsourcing and Social Computing* *May 2 * Mixel Kiemen (ECCO, GBI) *Design thinking for Evolutionary cybernetics: introducing artificial evolution by sensory-‐motoric workspace * *May 9 * Cliff Joslyn *Modeling Global Control Systems: Formal Approaches to Understand What a Global Brain Could Be * *May 16 * Abraham Bernstein (University of Zurich) *Programming the Global Brain - Implications for Computer Science* *May 23 * Shima Beigi *A generic framework for resilience of complex adaptive systems* *May 30* Mehdi Moussaid (Max Planck Institute for Human Development) *Social influence and collective opinion dynamics* *June 13* Alfonso Molina *June 20 * Piet Holbrouck (ECCO) *Problem Solving and Paradigm Shifts* *June 27* Viktoras Veitas & David R.
