Query: Boundedness of Pseudo-Differential Operators on $L^p$, Sobolev, and
  Modulation Spaces   We introduce new classes of modulation spaces over phase space. By means of
the Kohn-Nirenberg correspondence, these spaces induce norms on
pseudo-differential operators that bound their operator norms on $L^p$-spaces,
Sobolev spaces, and modulation spaces.
