The helmholtz decomposition theorem

WebNov 12, 2015 · It is demonstrated that it is quite simple to prove the Helmholtz decomposition in a more complete form than is found in any textbook. Sometimes surface charges and surface currents are missing in the theorem, although they may be important for physical issues. It is useful to know the limits for the strict uniqueness of the … WebA big result from vector calculus is the Helmholtz Decomposition: for any vector-valued function F: R 3 → R 3 that is well-behaved enough, we can always decompose it as follows: F ( r) = − ∇ Φ ( r) + ∇ × C ( r) There always exist functions Φ: R 3 → R and C: R 3 → R 3 for any choice of such F.
