The Local Möbius Equation and Decomposition Theorems in Riemannian Geometry

Canadian Mathematical Bulletin, 2002
AbstractA partial differential equation, the local Möbius equation, is introduced in Riemannian geometry which completely characterizes the local twisted product structure of a Riemannian manifold. Also the characterizations of warped product and product structures of Riemannian manifolds are made by the local Möbius equation and an additional partial ...
