Asymptotic analysis of numerical wave propagation in finite difference equations / by Michael Giles, W.T. Thompkins, Jr.

"An asymptotic technique is developed for analyzing the propagation and dissipation of wave-like solutions to finite difference equations. It is shown that for each fixed complex frequency there are usually several wave solutions with different wavenumbers and the slowly varying amplitude of ea...
