SUMMARY:Topological chaos\, Chaos & Complex Systems Seminar\, Jean-Luc
  Thiffeault\, UW Department of Mathematics
DESCRIPTION:Topological chaos is a type of chaotic behavior that is `f
 orced' by the motion of obstacles in some domain. I will review two to
 pological approaches\, with applications in particular to stirring and
  mixing in fluid dynamics. The first involves constructing systems suc
 h that the fluid motion is topologically complex\, usually by imposing
  a specific motion of rods. I will discuss optimization strategies tha
 t can be implemented. The second is diagnostic\, where flow characteri
 stics are deduced from observations of periodic or random orbits and t
 heir topological properties.<br>
