The matrix 6*V/6a, 6.x, corresponds to our

**operator**F and is obviously self-adjoint, since it is symmetric. Our theory corresponds to a continuum of dimensions but

is otherwise algebraically the same. The proof of d) follows the remarks in c) with

In fact, it is readily verified that the

**operator**appearing on the left-hand side of (5.7) represents the total time derivative following the group velocity of the wave.
