WebBy definition, a tangent vector at p ∈ M is a derivation at p on the space C ∞ ( M) of smooth scalar fields on M. Indeed let us consider a generic scalar field f: sage: f = M.scalar_field(function('F') (x,y), name='f') sage: f.display() f: M → ℝ (x, y) ↦ F (x, y) The tangent vector v maps f to the real number v i ∂ F ∂ x i p: WebDefinition. Specifically, a vector field X is a Killing field if the Lie derivative with respect to X of the metric g vanishes: =. In terms of the Levi-Civita connection, this is (,) + (,) =for all vectors Y and Z.In local coordinates, this amounts to the Killing equation + =. This condition is expressed in covariant form. Therefore, it is sufficient to establish it in a preferred …
