WebWe investigate the stability properties for a family of equations introduced by Moffatt to model magnetic relaxation. These models preserve the topology of magnetic streamlines, contain a cubic nonlinearity, and yet have a favorable L2 energy structure. We consider the local and global in time well-posedness of these models and establish a … WebRequest PDF On Mar 7, 2024, Rafał Komendarczyk published On Woltjer's force‐free minimizers and Moffatt's magnetic relaxation Find, read and cite all the research you need on ResearchGate
