Harmonic and quasi-harmonic spheres [PDF]

Communications in Analysis and Geometry, 1999
Let \(M\), \(N\) be smooth compact Riemannian manifolds without boundary, \(m= \dim M\) and the sectional curvature of \(N\) is nonpositive, and \(\phi:M\to N\) be a smooth map. This paper deals with the following conjecture: Any weakly harmonic map of finite energy from \(M\) to \(N\) is smooth provided that there are no harmonic spheres \(S^l\) in ...
