From Wikipedia, the free encyclopedia. In physics and mathematicsin the area of vector calculusHelmholtz’s theorem[1] [2] also known as the fundamental theorem of rotatiknnel calculus[3] [4] [5] [6] [7] [8] [9] 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.

## Helmholtz decomposition

Thanks to the divergence theorem the equation can be rewritten as. Usage notes and limitations: For higher dimensional generalization, see the discussion of Hodge decomposition below.

Springer Series in Computational Mathematics. 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.

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. Trial Software Product Updates. This is machine translation Translated by. Retrieved from ” https: With Applications to Physics. GriffithsIntroduction to ElectrodynamicsPrentice-Hall,p. 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.

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.

This theorem is of great importance in electrostaticssince Maxwell’s equations for the electric and magnetic fields in the static case are of exactly this type. Select a Web Site Choose a web site to get translated content where available and see local events and offers.
