SLOWLY VARYING FUNCTIONS IN THE COMPLEX PLANE

WebbThe theory describes slowly varying wavetrains, with the oscillation locally in one of the normal modes of a waveguide of quite general structure. The governing equations need not be hyperbolic; the wavelike character of the solution may be imparted by the lateral boundary conditions in the waveguide (e. g. surface waves on water).
