Conformal vector field
Web2. Let ϕ be a local flow of a vector field X on a Riemannian manifold ( M, g). We see that L X g = f g if a flow consists of conformal maps because of the formula: ( L X g) x = d d t ( ( ϕ t) ∗ g) x t = 0. Unfortunatelly I have a problem with showing inverse i.e. that L X g = f g implies that flow consists of conformal maps. differential ... WebSeasonal Variation.
