Conformal Vector Fields in Symmetric and Conformal Symmetric Spaces
Consequences of the existence of conformal vector fields in (locally) symmetric and conformal symmetric spaces, have been obtained. An attempt has been made for a physical interpretation of the consequences in the framework of general relativity.
متن کاملConformal vector fields and conformal transformations on a Riemannian manifold
In this paper first it is proved that if ξ is a nontrivial closed conformal vector field on an n-dimensional compact Riemannian manifold (M, g) with constant scalar curvature S satisfying S ≤ λ1(n − 1), λ1 being first nonzero eigenvalue of the Laplacian operator ∆ on M and Ricci curvature in direction of a certain vector field is non-negative, then M is isometric to the n-sphere S(c), where S =...
متن کاملCurvature Measures of 3D Vector Fields and their Applications
Tangent curves are a powerful tool for analyzing and visualizing vector fields. In this paper two of their most important properties are examined: their curvature and torsion. Furthermore, the concept of normal surfaces is introduced to the theory of 3D vector fields, and their Gaussian and mean curvature are analyzed. It is shown that those four curvature measures tend to infinity near critica...

متن کاملVector Commitments and Their Applications
We put forward the study of a new primitive that we call Vector Commitment (VC, for short). Informally, VCs allow to commit to an ordered sequence of q values (m1, . . . ,mq) in such a way that one can later open the commitment at specific positions (e.g., prove that mi is the i-th committed message). For security, Vector Commitments are required to satisfy a notion that we call position bindin...
