A vector Laplacian can be defined for a vector by
(1)
where the notation
is sometimes used to distinguish the vector Laplacian from the scalar Laplacian (Moon and Spencer 1988, p. 3).
In tensor notation,
is written ,
and the identity becomes
A tensor Laplacian may be similarly defined.
In cylindrical coordinates , the vector
Laplacian is given by

In spherical coordinates , the vector Laplacian
is
