Bibliotheca Neerlandica extra murosThe energy of a vector field X is the scalar field defined by f = .∥X∥. Thus the energy of a vector field is created by the vector field and by the Euclidean structure δ. of R.. The energy ƒ has interesting properties imposed either by the behavior of the gradient, Hessian or Laplacian of ., or by the behavior of . along field lines.
