Title: Another proof of the regularity of harmonic maps from a Riemannian manifold to the unit sphere Author: Junichi Aramaki (Tokyo Denki Univ., Saitama, Japan) Abstract: We shall consider harmonic maps from $n$-dimensional compact connected Riemannian manifold with boundary to the unit sphere under the Dirichlet boundary condition. We claim that if the Dirichlet data is smooth and so-called "small", all minimizers of the energy functional are also smooth and "small". Submitted September 16, 2013. Published January 27, 2014.
