DESCRIPTION:Transition to turbulence in cylindrical pipe flow is still not
  a well understood phenomenon. However\, Direct numerical simulation in pi
 pes with periodic boundary conditions shares a lot of common features with
  recent experiments. Here we are interested in the structure of the lamina
 r-turbulent boundary\, the manifold in phase-space separating the initial 
 conditions leading to turbulence from those who lead to quick relaminarisa
 tion. Depending on the symmetries of the problem\, phase-space trajectorie
 s on this manifold approach transiently various travelling wave solutions 
 sitting on it. We can study the implications of this on the transition pro
 blem for both short and long pipes.
