PROPAGATION AND STABILITY OF WAVELIKE SOLUTIONS OF FINITE-DIFFERENCE EQUATIONS WITH VARIABLE-COEFFICIENTS

PROPAGATION AND STABILITY OF WAVELIKE SOLUTIONS OF FINITE-DIFFERENCE EQUATIONS WITH VARIABLE-COEFFICIENTS

An asymptotic approach is used to analyze the propagation and dissipation of wavelike solutions to finite difference equations. It is shown that to first order the amplitude of a wave is convected at the local group velocity and varies in magnitude if the coefficients of the finite difference equati...
