Abstract: Over the past period of a decade and more, mathematicians in the PDE community have developed techniques for the phase space analysis of the dynamics of many model nonlinear Hamiltonian PDEs. These results include constructions of KAM invariant tori, Birkhoff normal forms and Nekhoroshev stability theorems, and constructions of cascade...

One of the most characteristic features of turbulence in three-dimensional incompressible fluids is enhanced energy dissipation.Most attempts to explain this phenomenon appeal to the remarkable Lagrangian properties of vorticity for inviscid flows. I review some of the ideas that have been proposed, including vortex stretching, vortexreconnectio...
