Extremal Properties and Hamiltonian Structure of the Euler Equationsnol’d’s (1966.) nonlinear stability theorems and their recent extensions and applications. Finally, a class of algorithms is described that can find true energy and energy-momenta extrema (under isovortical perturbations) of the two- and three-dimensional Euler equations, when they exist.

Research Announcement on the “Energy” of Knotsto create an infinite energy barrier to crossings. This requires at least the potential described 1/r. below. Whether or not weaker potentials 1/r., . < 2 might yet determine gradient flows which respect topology (.., admit no crossings) is an open question.

Force-Free Magnetic Fields with Constant Alphaical constraints has to end up as a constant-alpha force-free field. In addition to Moffatt’s conclusion, we would suggest that the relaxation of the field under topological constraints is accompanied by a change of the shape towards a more symmetric geometry of the domain.

Stretching and Alignment in General Flow Fields: Classical Trajectories from Reynolds Number Zero to Infinityd. The processes that are a consequence of having a given velocity field, irrespective of its origin, is the subject matter of .. The processes that govern the velocity field itself is the topic of . — in the case of fluids this dynamics is governed by the Navier-Stokes equation.
