Transport in Hamiltonian Systems

How does a blob of initial conditions evolve under a Hamiltonian flow? How do we characterize such a motion, composed of regular and chaotic components? These questions arise in diverse fields such as celestial mechanics, mechanical systems, Lagrangian advection in fluids and geophysics, and particle confinement in plasma. Here, fundamental mechanisms governing transport and their applications will be discussed; the role of self-similarities, of partial barriers and of degeneracies in two, three, and four dimensional maps and flows will be revealed. Finally, the implications of such theories on observable transport in fluids will be discussed.
