Title:
Renormalisation of period-doubling for volume-preserving flows
Speaker:
Abstract:
After some reminiscences about Feigenbaum and a review of our paper on period-doubling in area-preserving maps, I will recall my proposal for a period-doubling renormalisation operator on volume-preserving vector fields. I will flesh it out and emphasise how it fits with the Feigenbaum-Sullivan strategy of turning the scaling properties of marginally unstable critical dynamics into those for hyperbolic dynamics, and pose the question of whether the view enables a formulation of renormalisation on smooth conjugacy classes.
