Jan 20: Moved most of last week's in-class tutorial in to the main channelflow tutorial. John G 2009-01-29 10:54

Feb 24: What I think would be useful:

  1. Present general plane Couette symmetry group
  2. Important isotropy groups of plane couette
    1. some portion of the 67-fold path
    2. the S group containing Nagata-Waleffe etc.
    3. how certain symmetries restrict kinds of solutions (rule out traveling waves)
  3. bifurcations and symmetry
  4. our ardent desire to quotient out the discrete and continuous symmetries

Feb 24: Please read prior to meeting: Halcrow et al. definitive discussion of symmetries of plane Couette (have a look at the version uploaded Feb 23 at 5:17pm). I assume that the study group has mastered ChaosBook Discrete time dynamics, Local stability and Cycle stability under Alex guidance, and I would be happy if you also understood Charting the state space and brought Qualitative dynamics for cyclists to within your comfort zone. — Predrag Cvitanovic 2009-02-23 12:10
