SUMMARY:Turbulence transition in shear flows: coherent structures\, edge s
 tates and all that - Eckhardt\, B (Philipps-Universitt Marburg )

DESCRIPTION:Pipe flow\, plane Couette flow and several other shear flows s
 how a transition to turbulence for flow rates where the linear profile is 
 still stable. The turbulent dynamics is transient\, so that the transition
  is related to the formation of a chaotic saddle in the state space of the
  system. The saddle is supported by exact coherent states and their hetero
 clinic connections. I will summarize the common features that appear acros
 s all these shear flows\, sketch the numerical techniques used to identify
  and track the relevant structures in the state space of the system and po
 int out possible applications beyond fluid mechanics.\n
