WebThe standard example for your situation is the radial flow with velocity. V → ( x, y) = x x 2 + y 2 ı → + y x 2 + y 2 ȷ →. more compactly written as V → = r → / r → 2 . This is a divergence free flow in R 2 ∖ { ( 0, 0) }. (Note that the flux through a circle centered at the origin is 2 π regardless of its radius.) In three-dimensional Cartesian coordinates, the divergence of a continuously differentiable vector field is defined as the scalar-valued function: Although expressed in terms of coordinates, the result is invariant under rotations, as the physical interpretation suggests. This is because the trace of the Jacobian matrix of an N-dimensional vector field F in N-dimensional space is invariant under any invertible linear transformation.
