This result states schoen-uhlenbeck partial regularity theorem for energy-minimizing harmonic maps: given m 2, let U R m be open, and let N be a compact smooth Riemannian manifold isometrically embedded in R q for some q N. Let u W 1,2 (U;N) be an energy-minimizing harmonic map,.... It is useful in harmonic map theory and elliptic regularity, where variational identities, curvature estimates, and compactness arguments control geometric objects.
