DESCRIPTION:Prof. Arjan van der Schaft\nLarge-scale distribution networks 
 arise in many application areas. Network flow theory often tends to focus 
 on the static throughput behavior\, without taking the dynamical storage p
 henomena into full account. In this talk we will describe a general port-H
 amiltonian framework for describing and analyzing the dynamical properties
  of distribution networks. This framework is rooted in classical theory of
  electrical circuits and mechanical networks\, while emphasizing open syst
 ems. We will furthermore establish some close similarities with consensus 
 dynamics of multi-agent systems. As a particular type of dynamical distrib
 ution networks we will focus on\nchemical reaction networks\, motivated by
  ongoing collaboration in systems biology. We derive a compact formulation
  that is exhibiting at the same time the structure of the graph of the che
 mical complexes and the stoichiometry of the network. This formulation all
 ows us to provide a surprisingly easy characterization of the set of equil
 ibria or steady states\, and their stability properties. In the final part
  of the talk we will discus ongoing recent work with regard to structure-p
 reserving model reduction of large-scale physical networks\, based on the 
 notions of Kron reduction and clustering.\nBio: A.J. (Arjan) van der Schaf
