CONSTANT BOUNDARY VALUE PROBLEMS FOR F-HARMONIC MAPS ON SIMPLY CONNECTED NON-POSITIVELY CURVED MANIFOLDS
Qiuyan Zhang · Journal of Mathematics · 2010
In this article,we study constant boundary value problems for F-harmonic maps on complete simply connected Riemannian manifolds with non-positive sectional curvature.By using Hessian comparison theorem,we obtain Liouville-type theorems.
