Let us start with scalar fields. Field equations are a type of differential equation: i.e., they deal with the infinitesimal differences in quantities between neighbouring points. Helmholtz's first theorem: The strength of a vortex filament is constant along its length. From Wikipedia, the free encyclopedia There are several theorems known as the Helmholtz theorem: Helmholtz decomposition, also known as the fundamental theorem of vector calculus Helmholtz theorem (classical mechanics) Helmholtz Decomposition of Vector Fields Dr. Christopher S. Baird University of Massachusetts Lowell 1. Introduction The Helmholtz Decomposition Theorem, or the fundamental theorem of vector calculus, states that any well-behaved vector field can be decomposed into the sum of a longitudinal (diverging, non-curling, the Helmholtz theorem (HT) (see e.g.

In physics and mathematics, in the area of vector calculus, Helmholtz's theorem, also known as the fundamental theorem of vector calculus, states that any sufficiently smooth, rapidly 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. It is called Helmholtz's theorem after the German polymath Hermann Ludwig Ferdinand von Helmholtz. Let us start with scalar fields. Field equations are a type of differential equation: i.e., they deal with the infinitesimal differences in quantities between neighbouring points.

Helmholtz’ Theorem Theorem Helmholtz’ Theorem. Let F(r) be any continuous vector ﬁeld with continuous ﬁrst partial derivatives. Then F(r) can be uniquely expressed in terms of the negative gradient of a scalar potential φ(r) & the curl of a vector potential a(r), as embodied in Eqs. (10)–(11). Hermann Ludwig Ferdinand von Helmholtz (1821–1894) Das Helmholtz-Theorem, auch Helmholtz-Zerlegung, Stokes-Helmholtz-Zerlegung oder Fundamentalsatz der Vektoranalysis, (nach Hermann von Helmholtz) besagt, dass für gewisse Gebiete ⊂ der -Raum als direkte Summe von divergenzfreien Funktionen und Gradientenfeldern geschrieben werden kann.

Helmholtz's second theorem A vortex filament cannot end in a fluid; it must extend to the boundaries of the fluid or form a closed path. Helmholtz's third theorem In the absence of rotational external forces, a fluid that is initially irrotational remains irrotational. Helmholtz's theorems apply to inviscid flows.

[5]and [6]) and for this reason it was believed by some people that some-thing must go wrong using it (notably Heras in [3]), and proposed new forms of the Helmholtz decomposition, such that the retarded solutions can be obtained out of it (see e.g. [8] and [3][7]).

The Helmholtz Decomposition Theorem, or the fundamental theorem of vector calculus, states that any well-behaved vector field can be decomposed into the A standard theorem of vector analysis due to Helmholtz states that every vector field Thus the preceding Helmholtz theorem can be viewed as a theorem about . Helmholtz's theorem states that a vector field is determined to within an additive constant if both its divergence and curl are specified everywhere [14].
