Abstract
The pseudodifferential operators provide a unified treatment of differential and integral operators. They are based on the intensive use of the Fourier transformation \(\mathcal{F}\) (3.1.12) and its inverse \(\mathcal{F}\) –1 \(=\mathcal{F}\)*(3.1.14). The linear pseudodifferential operators can be characterized by generalized Fourier multipliers, called symbols.
