Rational Lawmaking under Review the mapping is an isometry, the tension field becomes none other than the mean curvature vector field. A harmonic map is one for which the tension field is zero, so that an isometric harmonic map has zero mean curvature, i.e. the image is a minimal surface. Considerable interest has been shown duri

Mark D. Terjesen Ph.D.,Maria A. Espositobe: Does there exist a conformal metric for which the scalar curvature is constant? And also problems posed by Chern, Nirenberg and others. All these problems are almost entirely solved, however there remain some open questions (see the conjectures).

The loop space homology algebrasics, we were led to study the actions of a group of transformations of a manifold . (the space-time in general relativity) on the sections of a vector bundle over . (the tensor or spinor fields of a given type). Several equivalent characterizations of these actions are given. A similar study is made for a Lie algebra of vector fields.

Fair Division under Asymmetric Informationfollows originated in attempts to understand the notions of . and . for bodies in space, it turns out that the ‘mobile’ and ‘comobile’ morphisms that we define occur throughout mathematics. Indeed, they are to be found in any categories between which there is a pair of adjoint functors.
