Finite-time singularities of the Navier-Stokes equation is a Millenium Prize problem (, and has significant consequences for theories of  vortex reconnection and fluid turbulence. The analogous problem of current singularities (whether finite-time or not) has deep implications for fast magnetic reconnection and plasma turbulence. Such current singularities, even when regularized by dissipation, have significant physical implications for problems as diverse as stellar coronal heating (Parker problem) and turbulence, neutron star mergers (including general relativistic effects), space weather, and last but not least, three-dimensional magnetohydrodynamic equilibria in toroidal plasmas which play a critical role in determining optimum topologies for magnetic confinement. A recent multi-institutional research program led from Princeton University and supported by the Simons Foundation on “Hidden Symmetries and Fusion Energy” ( provides a great and timely opportunity to bring together a diverse group of computational physicists, fluid dynamicists, mathematicians, and  plasma physicists to discuss problems of common interest at this Workshop.
