On ``spherical'' domains (the interior and exterior of a sphere, or in
a spherical shell) the completely general solution to the HHE can
therefore be written in *stationary* form as:

(11.105) |

(11.106) |

[This should provoke deep thoughts about the fundamental significance of the Laplace equation. Are there any ``really'' stationary sources in the dynamical, covariant, universe? Do we expect to have a contribution to the zero frequency charge/current density distribution in any region of space? What would this correspond to?]
