Understanding the properties of 3D MHD equilibria is essential for both stellarators and tokamaks. In the absence of axisymmetry, magnetic fields admit a variety of rich topological structures that can profoundly impact transport and confinement properties in fusion plasmas. Over the years, numerous classes of smooth and non-smooth MHD equilibria have been proposed, particularly for 3D equilibria. Non-smooth equilibria can admit structures including discontinuous pressure profiles and current densities, for which the physical interpretation and implications remain to be fully understood.
