Regularity for \(n\)-harmonic maps
The authors first establish a regularity theorem of some nonlinear elliptic systems with borderline growth, using a blow-up argument. As an application, the authors obtain everywhere regularity of \(n\)-harmonic maps with constant volume between manifolds. Other results concerning regularity up to the boundary and removability for isolated singularities are also obtained.
