"The term "Helmholtz theorem" can also refer to the following. Let C be a solenoidal vector field and d a scalar field on R which are sufficiently smooth and which vanish faster than 1/r at infinity. Then there exists a vector field F such that if additionally the vector field F vanishes as r → ∞, then F is unique. In other words, a vector field can be constructed with both a specified divergence and a specifie… " - Helmholtz potential
