This authoritative text studies pseudo-differential and Fourier integral operators in the framework of time-frequency analysis, providing an elementary approach, along with applications to almost diagonalization of such operators and to the sparsity of Gabor representations for certain classes of dispersive equations. Moreover, modulation spaces are employed to study dispersive equations such as the Schroedinger, wave, and Klein-Gordon equations.
