 ">Compositional Modeling with Decorated Cospans</a>\nby John Baez (UC Rive
 rside - USA) as part of GEOTOP-A seminar\n\n\nAbstract\nOne goal of applie
 d category theory is to understand open systems: that is\, systems with a 
 boundary of some sort\, through which matter\, energy or information can f
 low in or out.   We can describe a large class of open systems using the m
 athematics of decorated cospans\, which we explain here.  In various examp
 les these ideas have been implemented in software.  An interesting example
  comes from stock-flow diagrams\, which are widely used in epidemiology to
  model the dynamics of populations. Although tools already exist for build
 ing these diagrams and simulating the systems they describe\, we have crea
 ted a new package called StockFlow which uses decorated cospans to overcom
 e limitations of the existing tools.  This is joint work with Xiaoyan Li\,
  Sophie Libkind\, Nathaniel Osgood and Evan Patterson.\n
