Laplacian vector field
|This article does not cite any sources. (November 2009)|
In vector calculus, a Laplacian vector field is a vector field which is both irrotational and incompressible. If the field is denoted as v, then it is described by the following differential equations:
From the vector calculus identity it follows that
that is, that the field v satisfies Laplace's equation.
Then, since the divergence of v is also zero, it follows from equation (1) that
which is equivalent to
Therefore, the potential of a Laplacian field satisfies Laplace's equation.
