Definition

A smooth vector field on a differential manifold can be defined in any of the following equivalent ways:

  • It is a derivation from the algebra of C^\infty functions on the manifold, to itself
  • It is a section of the tangent bundle, which is a smooth map
  • it is a rule that associates (smoothly) to every point in the manifold a tangent vector
