%A Isabel Salavessa %T Graphs with parallel mean curvature and a variational problem in conformal geometry %X This thesis essentially deals with two basic problems, one in Rieinannian, the other in Conformal Geometry, described in Part I resp. Part III. Part II can be considered as an interlude serving as a sort of bridge between Riemannian and Comformal Geometry.
