The existence of such solutions depends heavily on the geometry of the manifold and, in the case of complete and simply connected Riemannian manifolds, we prove the existence under assumptions on the sectional curvature. In the first and fourth article we study the existence of minim... VO - IS - SP - OP - KW - N1 - PP - ER -
