Helmholtz decomposition – Wikipedia
With Applications to Physics. By William Woolsey Johnson. In other words, a vector field can be constructed with both a specified divergence and a specified curl, and if it also vanishes at infinity, it is uniquely specified by its divergence and curl.
Based on your location, we recommend that you select: Retrieved from ” https: Most formulations of the Hodge decomposition require M to be grsdient.

X and Y must have the same number of elements, as if produced by meshgrid. A terminology often used in physics refers to the curl-free component of a vector field as the longitudinal component and the divergence-free component as the transverse component.

For higher dimensional generalization, see the discussion of Hodge decomposition below. Then decompose this field, at each point kinto two components, one of which points longitudinally, i.

The Hodge decomposition is closely related to the Helmholtz decomposition, generalizing from vector fields on R 3 to differential forms on a Riemannian manifold M.

However, the compactness restriction in the usual formulation of the Hodge decomposition can be replaced by suitable decay assumptions at infinity on the differential forms involved, giving a proper generalization of divergenfe Helmholtz theorem.
Then there exists a vector field F such that. From Wikipedia, the free encyclopedia. It is named after Hermann von Helmholtz.
So far, we have. By Wesley Stoker Barker Woolhouse. Arfken and Hans J. The Helmholtz decomposition can also be generalized by reducing the regularity assumptions the need for the existence of strong derivatives.
