The Fourier transform of a scalar field is a scalar field, and the Fourier transform of a vector field is a vector field of same dimension. This page has been translated by MathWorks.

The Helmholtz decomposition can also be generalized by reducing the regularity assumptions the need for the existence of strong derivatives.
Then there exists a vector field F such that.
In physics and mathematicsin the area of vector calculusHelmholtz’s theorem  also known as the fundamental theorem of vector calculus       states that any sufficiently smoothrapidly decaying vector field in three dimensions can be resolved into the sum of an irrotational curl -free vector field and a solenoidal divergence -free vector field; this is known as the Helmholtz decomposition or Helmholtz representation.
The term “Helmholtz theorem” can also refer to the following. By Wesley Stoker Barker Woolhouse. This is machine translation Translated by.
Compute divergence of vector field – MATLAB divergence
With Applications to Physics. So far, we have.
Then decompose this field, at each point kinto two components, one of which points longitudinally, i. 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 the Helmholtz theorem.
It is named after Hermann von Helmholtz. 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. Click the button below to return to the English version of the page.

Gradient Divergence and Curl
San Diego pp. Founded on the Method of Rates Or Fluxions. Chelsea Publishing Company, The Hodge decomposition is closely related to the Helmholtz decomposition, generalizing from vector fields on R 3 to rtationnel forms on a Riemannian manifold M. By James Byrnie Shaw. From Wikipedia, the free encyclopedia. The American Mathematical Monthly.
Rotatjonnel 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. Thanks to the divergence theorem the equation can be rewritten as.
