Computation of Pseudo-Differential Operators
Symes, William W.
A simple algorithm is described for computing general pseudo-differential operator actions. Our approach is based on the asymptotic expansion of the symbol together with the Fast Fourier Transform (FFT). The idea is motivated by the characterization of pseudo-differential operator algebra. We show that the algorithm is efficient through analyzing its complexity. Some numerical experiments are also presented.
