The problem arises in the study of the dynamics of a magnetically confined fusion plasma in a Stellarator device when the dimensional analysis on the characteristic times suggests to neglect the inertial acceleration in presence of a time dependent magnetic field.engAn elliptic-parabolic equation with a nonlocal term for the transient regime of a plasma in a Stellaratorjournal articlehttp://www.sciencedirect.com/science/journal/00220396open access512.7Elliptic–parabolic problemRelative rearrangementFree-boundary problemPlasma physicsGeometria algebraica1201.01 Geometría Algebraica
